Is Gigantosaurus good in Commander?

Gigantosaurus in Commander — Combos, Decks & Price

Gigantosaurus is a 10/10 for five mana with no text box — just a wall of stats that demands an immediate answer or ends the game in two attacks. The cost is real: GGGGG means it lives exclusively in mono-green, but Ruxa, Patient Professor makes that restriction a feature rather than a bug.

Best Commanders

Commanders with the highest synergy

01

Ruxa, Patient Professor

90.1% of decks · synergy 0.85

Ruxa, Patient Professor wants creatures with no abilities, and Gigantosaurus is the platonic ideal — a 10/10 vanilla that gets a free buff from Ruxa's static and attacks as an 11/11 or larger once the anthem stacks. It shows up in over 90% of Ruxa decks for good reason.

02

Jasmine Boreal of the Seven

78.2% of decks · synergy 0.76

Jasmine Boreal of the Seven rewards you for running vanilla creatures with additional combat power, and Gigantosaurus is the biggest vanilla creature in the game — it's the headliner that Jasmine's anthem effects were built around.

03

Ghalta, Primal Hunger

54.0% of decks · synergy 0.48

Gigantosaurus contributes 10 power toward reducing Ghalta, Primal Hunger's commander tax, often making Ghalta castable for GG the turn after it resolves — that's two massive threats on the board in quick succession.

04

Selvala, Heart of the Wilds

27.5% of decks · synergy 0.22

Selvala, Heart of the Wilds generates one green mana for each point of power above the current highest — Gigantosaurus at 10 power almost guarantees a massive mana spike that lets you chain into the rest of your hand on the spot.

In Commander, Gigantosaurus is a role-player rather than a staple — it belongs in decks that specifically care about vanilla creatures or raw power counts, not as a generic green threat. In competitive 60-card formats like Modern and Pioneer, it never found a home because five mana for a do-nothing creature is too slow without a payoff attached. Legacy and Vintage have enough broken things happening that a vanilla 10/10 is irrelevant. Standard legality comes and goes with reprints, but even there Gigantosaurus sees virtually no constructed play outside of niche stompy brews looking for the highest power-to-mana ratio on a single card.

Price Context

unknown tier

Gigantosaurus has been reprinted enough times that copies are widely available and generally inexpensive — check Scryfall or your preferred retailer for the current price on whichever printing suits your deck. Given that its home is a narrow slice of Commander rather than any competitive 60-card format, there's no urgency to buy in ahead of a price spike.
