Ivern

Legend · PassiveWhen you conquer or hold, you may exhaust me to replace that battlefield with a Brush battlefield token. (Bird, Cat, Dog, Poro, and Ivern units have +1 Might in Brush. It can be swapped back when scored.)

Ivern rewilds the board. Green Father turns a battlefield you conquer into a Brush — its text gone, Ivern's friends a little stronger there — so his trials teach you which battlefield to rewild, and how a +1 in the Brush carries further than it looks.
