Death by Dragons

This spell can't be countered.
Creatures you control become dragons in
addition to their other types until end of turn.
They gain vigilance, flying, lifelink, first strike,
and trample, and they have base power and
toughness X/X until end of turn.
"You'll learn, my young apprentice, there are
many ways to die, but the purest death... is death by
dragons." -- Jo'N'Athan, Master Dracomancer
