Seraphic Steed - GW
Creature — Unicorn Mount
First strike, lifelink
Whenever Seraphic Steed attacks while saddled, create a 3/3 white Angel creature token with flying.
Saddle 4 (Tap any number of other creatures you control with total power 4 or more: This Mount becomes saddled until end of turn. Saddle only as a sorcery.)
2/2
Build your own Geist of Saint Traft. The first strike helps on this guy but the saddle cost seems high (obviously with 0 info on how saddle plays out yet!)
