Aelin Fireheart

First strike
Whenever Aelin deals combat damage to a player, you may create a legendary artifact token named The Amulet of Orynth with "tap, sacrifice this token : creatures you control get +2/+1 until end of turn"
When an opponent plays a legendary permanent, you may exile Aelin. If you do, search your library for a card named Celaena, Adarlan's Assassin and put it onto the battlefield
