JexInfinite, what do you suggest I include in my sideboard for Rain of Gore then? There are two shops I go to so technically there are two lgs meta's I have to adjust to. One is dominated by more infect, and the other is much more diverse. I feel like my worse matchups are decks that wreck faster than I do, such as affinity and infect, and decks running Leyline of Sanctity. I have Wear / Tear to use again the leyline, but for the other two matchups, I'm not quite sure.

I'm actually considering just splashing blue for Treasure Cruise and making this 4-color. I don't have any Steam Vents right now and am trying out either Reforge the Soul or Dangerous Wager for some card draw. Taking black, however, doesn't seem too ideal for me. I like having the black bolt as well as access to Rakdos Charm against aggro matchups and some affinity matchups.

Geist of Saint Traft is currently out of my budget (getting Goblin Guide come first) but an interesting suggestion. How useful is he as a SB option and against what would he come in? I've seen some burn SB lists run him but I'm not quite sure of his role in burn. Also getting both a blue and a white source can be kind of awkward, though I suppose that's the same for the double white for the Firewalker.

More blue for Treasure Cruise.

You really need Goblin Guides. Also, splashing blue for Treasure Cruise is much better than Reforge the Soul.

NateJH, I'm planning on it once I get a Steam Vents and more fetches.

vishnarg, yeah, I'm working on getting them but $80 for a playset is not easy to drop money for. What do you suggest I take out for the Guides when I get them? And for the cruise, I'm planning on it but my budget won't let me right now.

Well, Lavamancer has bad synergy with Treasure Cruise, and Goblin Guide could probably replace Reforge the Soul and Shard Volley in this build.

I noticed that about Grim Lavamancer and Treasure Cruise. I do like the Lavamancer though since the Lavamancer turns my graveyard into burn which is great late game. I'll probably remove them once I get the lands to include Treasure Cruise. Shard Volleys feed either the Lavamancer or Treasure Cruise so I'm not sure about removing them.
