The simple ability to cast a bunch of free spells is something thats worth building around, and its worth putting Abaddon into other decks too
Or do I get a Magic bar mitzvah at year thirteen
Between Snapcaster, Souls, delve, Goyf, and all the other graveyard-dependent cards (and strategies) of Modern, it's great to use cards that attack that resource
What you pay into it, it goes away though
-1 Morbid Opportunist: Good card but similar to Elas, I want to focus on ETB and Attacking rather than killing -1 Paladin Elizabeth Taggerdy: I don't want many of my creature cards attacking and honestly the CMC of many of my creatures doesn't make this card worth it -1 Pitiless Plunderer: Same as Morbid -1 White Glove Gourmand: Ended up being a card that read: 4 mana create 2 humans, which is not ideal Artifacts -1 Ashnod's Altar: Never really panned out how I wanted it to, make room for better cards Enchantments -1 Battle of Hoover Dam: Choosing NCR runs into the same issue as Alesha and Desmonda, choosing Legion is fine but also not amazing
Beyond the Squirrel tribal synergies, this deck is packed with ways to make tokens, fueling both Chatterfang and the wealth of other sacrifice outlets and powerful payoffs
