The Three-Headed Dog

When The Three-Headed Dog enters the battlefield, it deals 2 damage to target opponent.
Exile the top two cards of that player's library.
You may play those cards without paying their
mana costs. At the beginning of the next end
step, if any of those cards are still exiled, return
them to their owner's graveyard.
The Three-Headed Dog must be blocked if able.
