spinebiter mtg card Name: Spine, 28 cards The Gathering Spinebiter

Violent Outburst This is where the discussion gets easier, because the remaining cards are blatantly amazing

With both Twinning Staff and Alania on the battlefield, you'll be able to cast three separate instants of the spell

In Commander, where a valuable land is just a one-of in a hundred-card library, this can find you that Volrath's Stronghold, Academy Ruins, Strip Mine, or Maze of Ith that you need badly

Then the Punishment half is a Golgari X-costed sorcery that sweeps everything with that X cost of the artifact, enchantment and creature variety

That second activated ability makes a solid outlet for an absurd (or even infinite) amount of mana if you have a way to make that happen
