One of the best things about Commander being the most diverse of MTGs many formats, is that there are a nigh-on-infinite number of decks you can enjoy
If Bruse Tarl and Kraum are your commanders, your deck may contain cards with red, white, and/or blue in their color identity, but not cards with green or black
If you have one particular FF character that's close to your heart, these cards are a real treat
I have quite a few Enchantments in here because of course I do, and Ancestral Mask is going to do work
If we assume that both mana flood and mana screw are things that we'd like to avoid in order to have a fun game of Commander (and maybe even a chance at winning the game), then adding more MDFCs to your deck during deck building is the perfect solution to the problem
