Alduin the World-Eater

Menace, Flying, Trample, Haste.
All dragons you control gain +1/+1 and trample.
When Alduin deals combat damage to an opponent, you may pay {1}{w}{b}{g}{r}
to summon a 10/10 resurrected dragon token.

"You do not even know our tongue, do you? Such arrogance. To dare take for yourself,
the name of Dovah."
- Alduin
