D'akaru, the Pactbreaker

Whenever a creature an opponent controls dies, investigate. Then you win the game of you control
20 or more clues.
Whenever a creature an opponent controls attacks you, flip a coin. If you win the flip you may choose
a new target for the attack. If you don't choose a new target this way, untap that creature and remove it from combat.

And I shall start with your mind."
