@GutoCmtt @wfain Would you mind posting a list? It sounds like you are running the full 5 colors with Thalia, Pyroblast, DRS etc., and I'm interested to see how you allocated spots for ESG, DRS, and your lands. I've also been thinking a lot about off color moxen and a 5C list could potentially run all of them. I've found that emerald and pearl are great, while the rest go from game breaking on T1 to worse than a green producing land mid to late game.
Has anyone been trying Riftstone Portal recently? It was a staple of lists near the top of this thread, and kinda died off. I've been running a singleton and it has definitely been better than another fetch. If you are running DRS, I can see an extra fetch being more valuable, especially if you are color fixing for a 5C list.
