Gnasish, Elsewhere Warden

Whenever a card is put into exile from anywhere for the first time each turn, draw a card.
Whenever Gnasish dies, return each card you
own from exile to your hand.
Exile a card from your hand: Create an X/X Eldrazi creature token, where X is the converted mana cost of the exiled card.
As enigmatic as the Blind Eternities.
