Is Summoner's Grimoire good in Commander?

Summoner's Grimoire in Commander — Combos, Decks & Price

Summoner's Grimoire puts a free creature token onto the battlefield every time you cast a creature spell — the effect is immediate and cumulative, and it costs nothing beyond the initial investment of including it. Yuna, Hope of Spira decks treat it as a core piece, but any commander that floods the board with creature casts turns this into a passive token engine that snowballs fast.

Summoner's Grimoire is legal across every major format except Pauper, but Commander is where it actually gets played. In 60-card formats the effect is too slow and too conditional — you need a creature-dense shell and multiple casts to generate real value, and those formats have better engines for token generation. In Commander, casting creatures is just the normal rhythm of the game, so Summoner's Grimoire produces tokens passively without asking you to build around it. Oathbreaker is a reasonable secondary home if the planeswalker is creature-heavy, but the raw volume of creature casts in a 100-card Commander game is what makes this card matter.
