Void, Angel of the Godhand

Flying, trample

When Void, Angel of the Godhand enters, exile
cards from the top of your library until you exile a nonland card, then put that card into your hand.
If the card's mana value is 4 or greater, repeat this process. Void, Angel of the Godhand deals 1 damage
to you for each card put into your hand this way.

Everything is within the flows of causality.
