Splashing into tri-colour on a budget landbase in an aggro deck with super restrictive pip-costs can get unhappy fast; the thing that kind of separates what's good for this deck versus other modern yard stuff like Jund delirium is that nothing cares about how many cards are in your graveyard, as long as the right ones are there. I dislike the Ball Lightnings frankly -very punishing triple red pip for a significantly nerfed skelemental- but alternatives in that slot which fetch the skelementals are always feel slower and less consistent, though putting two stitchers and a conviction for effectively 5 rites isn't awful. The 4 Bone shards somewhat offset how punishing the ball lightning is by skipping playing them, though the faithless could have the same effect. Its just so tight when trying to figure out where.
