Yelad, Exemplary Extortionist

Hexproof
At the beginning of each opponent's end step,
if that player doesn't control a Blackmail token,
they create a colorless artifact token named
Blackmail with —
"{t}, sacrifice Blackmail: You lose 4 life."
As long as a player controls a Blackmail token,
if they would choose a card or player, you choose
those cards and/or players instead.
