Drache der`Zen

Flying, ward {2}
As long as your devotion to blue is less than four, Drache der`Zen isn't a creature.
When Drache der`Zen enters the battlefield, you
may draw three cards if you do discard two cards.
Whenever Drache attacks, you may cast a spell from your graveyard without paying its mana cost. If an instant or a sorcery spell was cast this way, return it to the bottom of your library instead.
