Bird of Paradise 4.0 In my first cube list back in Mirrodin block this would have comfortably made the top 5 creatures list
(To behold a Merfolk, choose a Merfolk you control or reveal a Merfolk card from your hand.) When this creature enters, create a 1/1 white and blue Merfolk creature token
It only quests for one lore, too, and its cost and stats are nothing to write home about
(If a creature with a finality counter on it would die, exile it instead.) Because you choose the target of Soulcoil Viper's ability before you pay the cost of sacrificing it, Soulcoil Viper can't be the target of its own ability
Good stuff in a deck that wants to use hard to block creatures to hit for effects
Liliana, Dreadhorde General Liliana, Dreadhorde General was one of my favorite planeswalkers back when it was legal in War of the Spark Standard
