Rise from flames

If X is 6 or more, you gain 6 life.

Return target creature with converted mana cost X
or less from your graveyard or exile to the battlefield and put your choice of a lifelink counter, a deathtouch counter, a vigilance counter, a flying counter or two +1/+1 counters on it.

That creature then deals 6 damage to all creatures, players and planeswalkers.
