Gemrazer enters the battlefield and immediately destroys an artifact or enchantment — you get a 4/4 reach trample threat and a removal spell stapled together, all for four mana. That's an exceptional rate in any shell that can copy or recur it, and commanders like Kiki-Jiki, Mirror Breaker and Otrimi, the Ever-Playful make that upside feel almost unfair.
Best Commanders
Commanders with the highest synergy
Otrimi, the Ever-Playful
Otrimi, the Ever-Playful returns Gemrazer from the graveyard to hand every time a mutated creature connects, turning a single copy into a repeating artifact-and-enchantment removal engine that reloads itself every combat.
Illuna, Apex of Wishes
Illuna, Apex of Wishes wants a high density of non-permanent spells and mutate creatures to flip into off the top, and Gemrazer fills both roles — it's a mutate creature that also clears the threatening enchantment or artifact sitting across the table the moment it lands.
Ivy, Gleeful Spellthief
Ivy, Gleeful Spellthief copies spells targeting single creatures, so a Gemrazer mutation targeting your own creature triggers Ivy and nets you a second mutate trigger — two artifacts or enchantments destroyed for the price of one cast.
Nethroi, Apex of Death
Nethroi, Apex of Death reanimates creatures with zero power from the graveyard, and Gemrazer's base power is 4 — but it mutates onto a zero-power creature, so you get it back as part of Nethroi's mass reanimation while the host qualifies for the effect.
Tatsunari, Toad Rider
Tatsunari, Toad Rider generates a Frog token whenever you cast an enchantment, and while Gemrazer isn't an enchantment itself, it destroys enchantments cleanly and its reach-trample body pairs well with the evasive token swarm Tatsunari builds.

Commander is where Gemrazer earns its reputation — the singleton format is packed with Rhystic Studies, Smothering Tithes, and Sol Rings, and Gemrazer answers all of them while contributing a relevant body to the board. In Modern and Pioneer, it's too slow at four mana for a format where Naturalize effects cost one or two, and creature-based removal gets outpaced by faster threats. Legacy has the same problem compounded: four mana is a lifetime. Gemrazer's real home stays firmly in 60-card casual and Commander, where the mutate upside and the 4/4 reach-trample chassis actually have time to matter.

Current price
$4.94 cheap tier
At $4.94, Gemrazer sits at the high end of the budget range but is still an easy include — you're paying for a two-in-one effect that pulls real weight in mutate and goodstuff Commander shells. The price is fair and unlikely to move much unless a prominent mutate commander spikes in popularity.
