Thryvll Dricorresh

Flash, Flying
Thryvll Dricorresh can't be countered
When Thryvll Dricorresh enters the battlefield,
return all attacking creatures to their owner's
hand. For each creature returned this way, draw
a card.
Whenever a player puts a creature on the battlefield, that player puts the top card of their library into their graveyard.
"I turn the tide of battle, even if it means turning
everyone away."
