Questions & Answers

FAQ

What is the best mana base for a Grixis Commander deck?

Grixis wants Xander's Lounge, Bloodstained Mire, Polluted Delta, plus Steam Vents / Watery Grave / Blood Crypt. Crumbling Necropolis + Nicol Bolas's tri-lands add support. Every Grixis deck should run Command Tower, Exotic Orchard, and a copy of Reflecting Pool. Beyond those, fill by budget: $50 = pain lands + tapped duals + basics; $100 = check lands; $250 = shocks + selective fetches; $500 = original duals + full fetch/shock synergy.

How many lands should a Grixis deck run?

A well-tuned Grixis Commander deck runs 36–38 lands. Sit at 37 by default. Fewer than 35 misses drops; more than 39 dilutes the game plan.

Which lands are auto-includes for Grixis?

Every Grixis deck runs Command Tower and Exotic Orchard. Reflecting Pool, Mana Confluence, and City of Brass become progressively more valuable the more colors you play. Always leave 1–2 utility land slots for the specific archetype.

Is it worth running fetch lands in Grixis?

Yes — Grixis benefits significantly from fetches because they thin your deck, fix your mana across three colors, and enable shock-land targets. At $250+ budget, run 4–6; at $500+, run 8+.
