What Jax Rewards

Grandmaster at Arms · printed ability

“1 Energy,: Attach a detached Equipment you control to a unit you control.: Attach an attached Equipment you control to a unit you control.”

Jax rewards resource timing; the Legend ability changes how confidently you can pay for your strongest turns.

How it plays

The Game Plan

Jax is not generic scaling. He attaches detached Equipment for energy or shifts attached Equipment for free, so the skill is deciding which unit needs the stats, protection, or keyword right now.

Strengths

  • Reuses Equipment across multiple units
  • Excellent with protection gear
  • Flexible combat math

Watch Outs

  • Needs Equipment to matter
  • Can lose tempo if gear is answered
  • Poor sequencing strands stats on the wrong unit

Turn by Turn

  1. 1Early: play cheap Equipment and bodies so Jax has movable material.
  2. 2Midgame: move gear onto the unit contesting the important battlefield instead of overcommitting to one carrier.
  3. 3Late: use Equipment mobility to keep your best stats relevant through removal, blocks, and battlefield swaps.

New to this Legend? Pick Jax if you want a gear deck where the same Equipment keeps changing carriers to win the next fight.
