Kha'Zix

Voidreaver

Body

ChaosIntermediate

Kha'Zix chooses which units fight, then turns successful combat into XP for the next decision. The difficult part is making those trades win points, not just look efficient.

Should you play Kha'Zix?

Pick Kha'Zix if you enjoy finding a favorable fight on a board that initially looks bad. Movement, temporary Might, and XP give you plenty of ways to change the terms.

Best for: Players who like manipulating both sides of the battlefield and reusing interaction while an established threat keeps scoring.
Think twice if: You want a simple curve or a Legend that saves you during the opponent's combat. Kha'Zix's XP activations need preparation on your own turn.

Key Cards

Void Assault is what makes the opponent's formation negotiable. It can move a friendly unit into the fight you want and move an enemy out of it, or send both to a different battlefield. Fizz gives you another use of that spell, a hand-disruption spell, or Star-Crossed while developing a body. Mutating Horror is still the chosen Champion, but these are the cards that keep the whole plan working after its first attack.

Kha'Zix’s Field Guide

Kha'Zix wants control over the fight before caring about the size of the fighter. Voidreaver gains one XP when you win combat. Spend one XP and exhaust the Legend to buff a unit, or spend two and exhaust it to move an exhausted friendly unit from a battlefield to base. Both abilities belong in an open Main Phase on your turn. They are not tricks to reveal once the opponent attacks. The buff is lasting +1 Might on a unit that does not already have one; the relocation saves the body but does not ready it. Those choices compete for the same Legend activation, so decide whether the next turn needs a stronger board or a unit brought safely home.

How Kha'Zix wins

Pull a manageable enemy into a fight your units can win, or move a reinforcement away so the remaining defender stops being a problem. Mutating Horror rewards an isolated enemy with +2 Might and two XP when it attacks or defends. That XP does not require victory, although the Legend's extra XP does. Once you have a useful attacker and a way to protect another battlefield, the movement cards can make the opponent defend the wrong place. Taking an empty battlefield is still a good point; it just is not a combat win. Do not drag an enemy into an otherwise free conquest solely to earn one XP.

Key interactions

Make isolation happen before counting on it

Kha'Zix, Mutating Horror · Void Assault · Irresistible Faefolk

Horror checks whether an enemy is alone when it becomes an attacker or defender. Void Assault can separate a pair of defenders, while Faefolk can pull one enemy along when it moves to a battlefield. Once Horror's isolation ability has triggered, a later Ambush unit does not cancel that bonus, but it can still turn the fight against you. A small Faefolk also needs help winning the fight it started. Void Assault costs two Energy and one Power from either Body or Chaos. It has no Action or Reaction tag, so set up that movement before the Showdown rather than waiting to use it as a combat response.

Use XP before the opponent asks the question

Demacian Diplomat · Grim Resolve · Voidreaver

Diplomat gives an XP on play, which means you do not have to win combat before the first buff. Grim Resolve takes the other route: +3 Might for the turn, then two XP if that unit wins a combat that turn. A surviving Horror that wins against an isolated enemy with Resolve can produce five XP altogether: two from isolation, two from Resolve, and one from the Legend. A mutual trade does not do that. Spend the resulting XP when it changes the next fight, and remember that Resolve's temporary Might is not a buff you can spend or keep next turn.

Bring back the answer you actually need

Fizz, Trickster · Star-Crossed · Sabotage

Fizz can replay a spell costing up to three Energy from the trash, ignoring that Energy but still paying its Power. Replaying Star-Crossed can return Fizz himself and an opposing unit to hand. You get another Fizz deployment later, but Star-Crossed is recycled, not left in the trash for an endless loop. Replaying Sabotage is often better when the opponent's non-unit answer is what prevents your next attack. Account for both payments: Fizz needs three Energy and one Chaos Power, then Sabotage needs one Body Power. Reusing a spell is valuable only if enough resources remain to convert it into a point.

Strengths

Movement can break up a defensive formation instead of asking every attacker to beat the opponent's whole board.
Early XP and combat XP serve the same plan. A lasting buff can make a cheap unit relevant, while a later relocation preserves a threat you have already paid for.
Fizz makes the trash a useful set of options. A second movement spell, hand disruption, or bounce can be more important than drawing another large unit.

Weaknesses

The Legend's activations cannot rescue an exhausted defender during the opponent's Showdown. Spending XP well requires planning before the threat arrives.
An isolation bonus is not a promise of winning combat. The opponent can add units after Horror triggers, and winning that fight still does not guarantee that the other battlefield remains safe.
Repeated Power payments can shrink the rune base quickly. A clever Fizz turn that leaves no resources for the following turn can still lose the game.

Shadow's take

This is my Kha'Zix pick because the movement and ready effects let the board keep earning useful fights. Faefolk and Void Assault can separate a defender from its support, while First Mate or Ride the Wind gives the attacker another action afterward. I like Qiyana as the follow-up: a conquest can supply a card or an exhausted rune instead of asking every resource turn to come from Horror's isolation trigger. Diplomat gets the first XP available, and Grim Resolve rewards a combat your unit actually survives. Spirit Wheel can turn a friendly choice into a draw, but its extra Energy and exhaust are still a payment. Spend that Energy when it improves the next turn, not when it leaves the current attack without the trick it needs.

The Game Plan

Early gameLook for Diplomat or Faefolk with a fighter to follow. Diplomat gives one XP on play, allowing the Legend's buff before the first combat. The buff needs an unbuffed unit to add another Might; it is different from a temporary increase. Faefolk pulls an enemy only when it moves to a battlefield, not when played there. A hand full of movement still needs the unit that will win the arranged fight.
MidgameUse Void Assault to move a friendly unit and then an enemy, arranging a battlefield where Horror can attack or defend against an isolated unit. Grim Resolve adds three Might and gives two XP when that unit wins a combat this turn; the Legend's ordinary combat-win XP is separate. Challenge and Rampage exchange unit damage without creating a combat win. Fizz can reuse your spells costing at most three Energy while still requiring their Power, so Onslaught does not qualify. Leave a rune for Spirit Wheel's extra Energy only when the resulting draw is worth delaying another play.
Late gameTurn the ready effects into the next point. First Mate readies another unit; Ride the Wind moves a unit and readies it. Qiyana's conquest can draw or channel an exhausted rune, while Trophy Hunter can enter a battlefield containing enemies. Keep another body where a Hold matters before using Star-Crossed to save your fighter. Tools of Empire gives two Might, or four once empowered, through a normal activation on your turn. It is not a Reaction to a pending answer.

Battlefields

Turn a buff into a card

Monastery of Hirana · Voidreaver

Hirana lets you spend a buff to draw when you conquer. The Legend can provide that buff for one XP and an exhaust, but spending it removes its Might from the unit. Keep the buff when it is what makes the next defense work.

Preserve a unit after the new arrival

Star Spring · Rengar, Trophy Hunter

The first non-token unit played here each turn can move another friendly unit here to base. An Ambush unit can provide that play during the opponent's attack. The moved unit is not readied automatically, and leaving no holder can give away the point.

Isolate the defender

Forbidding Waste · Void Assault

Waste reduces a lone defender by two Might. Moving its companion away can make Horror's isolation plan more effective, but your own lone defender receives the same penalty. Keep the return attack in view before moving the supporting body elsewhere.

Sideboard

Protect the commitment

Sabotage · Gust · Punch First

Sabotage removes a revealed non-unit card before your attack. Gust returns a battlefield unit with at most three Might, while the extra Punch First supplies five temporary Might for two Body Power. Trim an answer with no useful targets rather than cutting the units these cards need.

Change the threat they must answer

Gangplank, Naval · Ruin Runner

Ruin Runner cannot be chosen by enemy spells or abilities, but still takes combat damage. Empowered Gangplank replaces chosen stun, negative-Might, or return-to-hand effects with +3 Might; it does not protect him from every kind of removal. Bring the threat that addresses the actual interaction, replacing a slower or less protected top-end unit.

Interrupt the replay

Disposal Order

Disposal Order can recycle up to three cards from opponents' trashes as a Reaction, or draw a card instead. Use it before the important unit or spell has left the trash. Make room among less useful combat cards when repeated recovery is undoing your exchanges.
