Brilliant Ultimatum
Sorcery
Exile the top five cards of your library. An opponent separates those cards into two piles. You may play lands and cast spells from one of those piles. If you cast a spell this way, you cast it without paying its mana cost.

Brilliant Ultimatum lets you exile the top five cards of your library and cast any number of them for free — the catch is your opponent chooses which pile you get. At seven mana in three colors, the floor is real, but The Celestial Toymaker turns that opponent-controlled pile split into a feature rather than a flaw.

Commanders with the highest synergy
The Celestial Toymaker
The Celestial Toymaker's ability to manipulate what counts as a 'game' means the pile-split mechanic on Brilliant Ultimatum aligns perfectly with its gameplan of forcing opponents into lose-lose decisions — 73% of Toymaker decks include it for exactly this reason.
Yennett, Cryptic Sovereign
Yennett, Cryptic Sovereign can cast Brilliant Ultimatum for free off its trigger since it has an odd mana value of seven, turning what would be a seven-mana investment into pure upside.

Commander is where Brilliant Ultimatum lives — seven mana is a meaningful investment in a singleton format, but the raw card advantage from exiling five and casting multiples for free is exactly the kind of late-game swing that closes out tables. The pile-split drawback shrinks in multiplayer because you can engineer the five cards to be good in either pile, making the opponent's choice much harder. In Legacy and Vintage, it's technically legal but entirely unplayed; those formats end games before turn four, and a seven-mana sorcery that hands the opponent agency is not competing with the broken things those formats offer. Oathbreaker is a viable home for the same reasons as Commander, especially under a Esper planeswalker that can set up the top of the library.

Price Context
Current price
$1.60 cheap tier
At $1.60, Brilliant Ultimatum sits in the throw-it-in tier — the price creates no meaningful barrier for any Commander deck that wants it. That price point reflects casual demand rather than competitive relevance, so don't expect volatility in either direction.
