Monstrous Desert Cobra

Deathtouch
Whenever Monstrous Desert Cobra attacks while
saddled, another attacking creature you control gets
+X/+X and deathtouch, where X is the power you
saddled this Mount this turn.
Saddle {x} (Tap any number of other creatures you
control with total power X or more: This Mount becomes saddled until end of turn. Saddle only as a sorcery.)
