Is Rhonas's Monument good in Commander?

Rhonas's Monument in Commander — Combos, Decks & Price

Rhonas's Monument cuts the cost of every green creature spell you cast and pumps the team on each trigger — that's a repeatable, stackable effect that earns its slot in any creature-dense green deck. Commanders like Zask, Skittering Swarmlord and Ayula, Queen Among Bears generate enough creature casts to turn a three-mana artifact into an engine that effectively pays for itself within two or three turns.

Best Commanders

Commanders with the highest synergy

01

Ayula, Queen Among Bears

58.2% of decks · synergy 0.42

Every Bear you cast off Rhonas's Monument triggers Ayula, Queen Among Bears, and the cost reduction means you're chaining Bears faster — more triggers, more fights or counters, more board presence snowballing out of control.

02

Baru, Wurmspeaker

48.8% of decks · synergy 0.32

Baru, Wurmspeaker wants to cast large green creatures as often as possible, and Rhonas's Monument shaves a generic off each one while simultaneously buffing whatever just entered — straightforward rate improvement for a deck already built around that game plan.

03

Gargos, Vicious Watcher

47.3% of decks · synergy 0.31

Hydras are already expensive, and Rhonas's Monument stacks on top of Gargos, Vicious Watcher's own cost reduction, letting you land threats a full two or more mana ahead of schedule while the +2/+2 trigger keeps pressure on.

04

Fangorn, Tree Shepherd

43.2% of decks · synergy 0.27

Fangorn, Tree Shepherd cares about Treefolk and big green creatures, and Rhonas's Monument accelerates the clock by trimming costs and adding trample-relevant power bumps each cast — both effects point directly at what the deck wants to be doing.

05

Fynn, the Fangbearer

40.5% of decks · synergy 0.24

Fynn, the Fangbearer wins through deathtouch creatures connecting, and Rhonas's Monument lets you flood the board faster while the +2/+2 counters make those small deathtouch bodies harder to chump-block into irrelevance.

Rhonas's Monument is a Commander card — full stop. In creature-heavy green decks, the cost reduction compounds across a long game in ways that shorter formats simply don't allow. In Modern and Pioneer, three mana for a do-nothing artifact that requires you to already be casting creatures is too slow when you could just run more threats. Legacy has the redundancy and power ceiling to ignore it entirely. Commander is where the math works: enough creature casts over enough turns, and Rhonas's Monument generates substantial effective mana while the triggered pump keeps board states lopsided.
