Mike, Patricia's Innkeeper

If a spell or ability would target Mike, counter it unless its controller pays 3 life.

When Mike enters or attacks, create a Beer token. (It's a colorless artifact token with "{t}: Roll a d6. Target creature you control gets +X/-X until end of turn, where
X is half the result, rounded up. If you rolled a 6, that creature also gains indestructible until end of turn.")

If Mike's power is greater than his base power, other creatures you control get +X/-X where X is the difference.
