Oberon, Architect of Mind

Tribulation (Whenever this creature deals combat
damage to a player, that player mills the top card
of their library.)
Whenever an opponent mills a card, you may pay {1}{u/b}. If you do, Oberon deals 2 damage to any
target, and you create a 1/1 Wraith token.
"Devil's only do their deeds in deals."
