Tomb of Dragons enters the battlefield tapped.

{t}: Add {r}, {g}, or {b}.

Whenever a creature you control dies, pay {6}. If you do, return it to the battlefield at the beginning of the next end step, with a +1/+1 counter on it and with flying. It is a dragon in addition to its other type.

"In the tomb's dark embrace, death is but a moment. The dragons' flame forges those who fall."
— Orath, the Mana Seeker
