The Minnow Booster is a summoner of a special team made up of cards of any element.
This is the commander of the legions of the invisible, of the despised, of the powerless. His power acts on level 1 cards with less than 3 hearts that do not have shields.
It makes everyone attack the front enemy at the same time !
But.. don’t look for it on the market. It’s a very very very special edition of one. And can’t play. Lol
