Aellyre, Warmother Reborn

Flying, vigilance, haste, trample
Creatures you control have first strike.
At the beginning of your upkeep, if you control three or more creatures that share a creature type, you may return Aellyre, Warmother Reborn from exile or your graveyard to your hand. If you control three or more legendary creatures that share a creature type, you may put it onto the battlefield instead.
