Tsunade, Hokage of The Leaf

Tranple

Whenever Tsunade attacks, you may reveal the top card of your library. If you do, every other player must reveal the top card of their library as well. The player that reveals the card with the highest converted mana cost creates a food token and a treasure token.

If you have the least life, Tsunade gets +2/+2 and has regenerate.
