Firemind's Foresight

Commander is where Firemind's Foresight actually lives — the singleton format rewards tutors that fetch multiple specific pieces at once, and a seven-mana spell that grabs an entire three-card combo line is a reasonable late-game play even at full price. In spell-cost-reduction shells it becomes busted, which is why its EDHREC numbers are driven almost entirely by Izzet spellslinger commanders. In Legacy and Vintage, seven mana is a non-starter; cheaper, more flexible tutors make Firemind's Foresight irrelevant in those formats. Modern and Pioneer are similarly hostile — the curve is too high and the payoff too narrow compared to what those formats offer. Stick to Commander, specifically any deck that already wants to chain instants.
