Dread Scale Drake

Lifelink, Flying
Madness {1}{b}: (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)
If a Dragon creature dies on the battlefield, put a +1/+1 counter on Dread Scale Drake.
Scavenging the remains of its dead cousins is only a natural instinct. But so is destroying everything it passes.
