Killer Weed

So this is based on Invasive Species Swarm by Dragonite04, but going into Elysian. Not sure if that's right, but I haven't seen it done yet and Invasive Species really doesn't care about being in Shadow. Plus, all the good killer decks are Elysian.

Very broad strokes. I feel confident about Pitfall Trap, Twilight Hunt, Alhed Ascending, and Savagery being good. Not enough Primal for Savagery, but whatever.

Any thoughts? We've seen some killer killer decks for gauntlet, so I'm sure somebody's got something to critique.
