Ivern

A Bird, Cat, Dog and Poro on your board are the four tags that Friendship and Daisy care about, and Trusty Ramhound is the only Dog in this list. Three Birds still count as one distinct tag. Protecting your last Dog can matter more than adding another duplicate Cat to the fight. With all four tags, Friendship gives +4 Might for one Energy and Daisy's Energy cost falls from nine to five. Daisy still costs two Power. If the last Dog disappears, recount before spending the resources or planning the attack.

Mouser's Tank means it must receive lethal combat damage before your other units without Tank. That can keep Nurturer alive or leave Affectionate Poro untouched for its end-of-combat draw. Block can give a different unit Shield 3 and Tank for the turn, so it is in front of your units without Tank, though with Mouser also there the opponent can choose either Tank and enough damage can still kill it. Poro needs to have taken no damage at all that turn; healing damage afterward does not restore the draw condition. Nurturer also does not guarantee a card or buff every time. It needs a unit among the three, and the extra buff needs a Bird, Cat, Dog, or Poro reveal. Put that buff on a unit that does not already have one and needs the extra Might for its job.

Replacing a battlefield with Brush does not move its units, ready them, or create another conquest. It gives Bird, Cat, Dog, Poro, and Ivern units there +1 Might and removes the original battlefield's abilities while Brush remains. The opponent's qualifying units receive the same bonus. When either player later scores at Brush, that player may restore the original battlefield. Keep that possibility in mind if your next play depends on a restriction staying gone. The Legend also has to exhaust for the conversion, so you cannot change both battlefields from consecutive scores unless something readies it in between.
