Portgas D. Ace, Fire Fist

Menace
Whenever one or more Pirates you control
deal damage to you opponents, exile the top
card of each of those opponents libraries.
You may play those cards this turn, and you
may spend mana as though it were mana of
any color to cast those spells.
"I don't wanna live a thousand years. If I just
live through today, that'll be enough."
