Although you have to lose the dork to kill a thing unlike Viridian Shaman you are not constrained by keeping it back until needed and are therefore able to curve out nicely with it
I know, not bad at all here and all
Into the Roil Rarity: Common TYPE: Instant SUBTYPE: - CMC: 2 Mana cost: USD: $0.10 EUR: 0.08 TIX: 0.03 EDHREC RANK: 5307 Kicker (You may pay an additional as you cast this spell.) Return target nonland permanent to its owner's hand
All of them are the same card mechanically, but feature different art with new suits
(If a creature with a finality counter on it would die, exile it instead.) So, fairly self-explanatory here, if a permanent has a Finality Counter on it, and that permanent would die, it doesn't hit the graveyard
EDIT: See this video, specifically game 1 of match 3, for a great example of Snapcaster Mage being used as a finisher.
