2Infernal Plunge--->2 Pyretic Rituals
2 Memnites -->2 Faithless Looting
While playing fetch lands in a mono-colored deck probably seems strange, the free shuffle they offer works extremely well with frenzy—when we hit our second land for the turn, we can simply shuffle it away by cracking a fetch—while also removing a land from our deck, reducing our odds of hitting another in the future. Otherwise, in the sideboard, we get Blood Moon to jank our opponents out of the game along with a couple of Surgical Extraction as combo hate that also happens to be a free spell to cast while we are frenzying.
