Mist Dancer comes back from the grave with a vengeance, granting all your flying Merfolk an extra three power for the turn, and perhaps letting you close out the game
On his face side, he is Mono-white 3/3 for four that removes a tapped vehicle or creature when he attacks, granted the owner can re-play it, but if it doesnt have flash this is a mini temporary removal spell
(At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.) Whenever you win a coin flip, this creature deals 1 damage to any target
As such, they will deal damage when blocking
Rienne makes removal less scary, since every threat you lose comes back ready to be replayed
As a creature, technically, Mondrak, Glory Dominus isnt quite as good as Anointed Procession since theyre more subject to removal
