Untimely Malfunction is a spell worth playing if you have not yet slotted it in a deck
From an artifact creature Storm deck to Temur beat-down, the options are limitless, and Id highly recommend this commander for new players
Ruby Storm with Ruby Medallion will be tried, although it lacks the rituals it has in Legacy
This Final Fantasy commander deck for MTG is Naya on the color pie, meaning it runs cards that contain Green, Red, and White mana
This two-mana artifact can tap for one mana of any colour in your commanders colour identity
So if your Commander is Red and White, then you cannot have any Blue, Black, or Green cards in your deck (and the rules also dont let you cheat and use colored abilities either)
