Heklyn, Court Jester

When Heklyn, Court Jester enters the battlefield,
target opponent becomes the monarch.
Haste, deathtouch, ward {3}
If you would become the monarch, instead look
at the top three cards of the monarch's library,
exile one of them face down, then put the rest
back in any order. Until your next turn, you may
cast the exiled card. When you do, target
opponent becomes the monarch.
