Flying, lifelink

Reach
{T}: Adorned Flamebinder deals 1 damage to any target. Activate only if Adorned Flamebinder is embattled. (A creature is embattled if it has a counter on it or a permanent you control attached to it.)

Entropic Inferno deals 5 damage divided as you choose among any number of targets. At the beginning of the next end step, for each permanent dealt damage this way, its owner puts it on the bottom of their library, then reveals cards from the top until they reveal a nonland permanent card. They put that card onto the battlefield, then shuffle.

Marrowskitter can't block and can't be blocked.
{3}{B}{B}: Return Marrowskitter from your graveyard to the battlefield. Create a token that's a copy of it.

Flying

All damage that would be dealt to target creature you control this turn is dealt to another target creature you control instead. Both those creatures get +1/+1 until end of turn.

Destroy target creature or planeswalker.

Whenever you sacrifice a permanent, you may put a soul counter on Soul's Guidestone.
As long as there are five or more soul counters on Soul's Guidestone, it's a 6/6 Golem artifact creature with menace and vigilance.

Whenever you cast a noncreature spell, you may tap or untap target permanent.
