Kaiyo, Recaller of Sin

When Kaiyo enters the battlefield, you may exile
a creature card from your graveyard. If you do,
put three sin counters on Kaiyo.
{u}, Remove a sin counter from Kaiyo: Kaiyo
gains all abilities of a creature card exiled with it
until end of turn. Then, if there are no sin
counters on Kaiyo, draw three cards. Activate
only once each turn.
