Bayle, Dread to All

Flying

At the beginning of your end step, if creatures you control have total toughness 10 or greater, draw a card. Then, if creatures you control have total toughness 20 or greater, untap each creature you control. Then if creatures you control have total toughness 40 or greater, each opponent loses half their life, rounded up.

Bayle was the foul dragon's name — a terrible harbinger of destruction whose challenge to the ancient Dragonlord ended in grievous mutual injury.
