Is Octopus Form good in Commander?

Octopus Form in Commander — Combos, Decks & Price

Octopus Form turns any creature into a 8/8 blue Octopus with shroud, wiping its previous abilities in the process — removal and finisher stapled together for six mana. The cost is real, but Iroh, Grand Lotus decks recoup it by casting Octopus Form from the graveyard, making that six mana a repeatable threat rather than a one-time play.

Commanders with the highest synergy

01

Iroh, Grand Lotus

69.8% of decks · synergy 0.62

Iroh, Grand Lotus makes Octopus Form absurd: Iroh's ability lets you cast it from the graveyard whenever a creature deals combat damage to a player, turning a single copy into a recurring board-warping threat that rebounds every time your team connects.

02

Sokka, Tenacious Tactician

33.2% of decks · synergy 0.30

Sokka, Tenacious Tactician rewards playing high-impact blue spells, and Octopus Form doubles as a combat trick and creature transformation that fits neatly into the aggressive tempo gameplan Sokka, Tenacious Tactician wants to run.

03

Katara, Waterbending Master

34.0% of decks · synergy 0.30

Katara, Waterbending Master cares about casting spells with water magic flavor and recurring value, and Octopus Form slots in as a high-impact aura that advances both the thematic and mechanical goals of a Katara, Waterbending Master build.

04

Katara, the Fearless

27.0% of decks · synergy 0.25

Katara, the Fearless benefits from spells that generate immediate board impact, and Octopus Form's combination of removal and evasion-granting transformation gives Katara, the Fearless a tool that pulls double duty in combat.

05

Alaundo the Seer

19.5% of decks · synergy 0.19

Alaundo the Seer suspends cards and converts them into free casts, so Octopus Form's six mana becomes irrelevant — Alaundo the Seer turns it into a zero-cost board swing that can close out a game the turn it resolves.

Format	Verdict

legacy	legal
modern	legal

vintage	legal
pauper	legal
oathbreaker	legal

Commander is where Octopus Form does its best work, primarily because of the Iroh, Grand Lotus synergy that makes it a reusable engine rather than a one-shot aura. In 60-card formats like Modern and Pioneer, six mana for a single-target aura that loses to enchantment removal is too slow and fragile — those formats want interaction that doesn't die to a Disenchant. Pauper is legal but the same tempo problem applies at even lower power floors. Legacy and Vintage have no interest in a six-mana do-nothing against fast combo. Octopus Form is a Commander card through and through.

Price Context

Current price

$0.20 bulk tier

At $0.20, Octopus Form is pure bulk — easy to pick up as a four-of or to trade for without a second thought. Given its narrow Commander home in Iroh, Grand Lotus decks specifically, don't expect the price to move unless that commander sees a significant spike in popularity.
