Stormtide Leviathan card art
Stormtide Leviathan hits the table and immediately locks every non-Island land out of the combat step — eight power of islandwalk beats swings through anything that can't block, and the board-wide flight restriction shuts down most creature attacks in return. The cost is real: eight mana is a steep ask outside dedicated ramp or cheat shells, and a single removal spell erases the lock. Pair it with Archetype of Imagination for a redundant evasion layer, or let Runo Stromkirk put it into play ahead of curve.

Best Commanders

Commanders with the highest synergy

01

Runo Stromkirk

74.9% of decks · synergy 0.73

Runo Stromkirk can flip into Krothuss and copy Stormtide Leviathan on attack, doubling the board-lock and the islandwalk threats in a single combat step. At 75% inclusion across Runo lists, Stormtide Leviathan is effectively a staple here.

02
Kenessos, Priest of Thassa

Kenessos, Priest of Thassa

70.3% of decks · synergy 0.65

Kenessos, Priest of Thassa cheats Sea Creatures directly into play from the top of the library, and Stormtide Leviathan is one of the highest-impact targets he can land for free. It immediately warps the combat step the turn it arrives, which is exactly what a tap-and-pray effect wants as a payoff.

03
Kiora, Sovereign of the Deep

Kiora, Sovereign of the Deep

62.4% of decks · synergy 0.57

Kiora, Sovereign of the Deep triggers whenever a Kraken, Leviathan, Octopus, or Serpent enters the battlefield — Stormtide Leviathan qualifies and delivers a board-lock on the same turn it generates a cascade. That's two independent sources of value from one card slot.

04
Braids, Conjurer Adept

Braids, Conjurer Adept

58.0% of decks · synergy 0.51

Braids, Conjurer Adept puts any permanent from hand into play for free at the beginning of each player's upkeep, and Stormtide Leviathan is one of the most punishing things to drop on an opponent's board without warning. The lock lands before they can declare attackers.

05
Xolatoyac, the Smiling Flood

Xolatoyac, the Smiling Flood

43.5% of decks · synergy 0.38

Xolatoyac, the Smiling Flood cares about Leviathans and turning lands into Islands, which directly synergizes with Stormtide Leviathan's islandwalk condition and the combat restriction it imposes. The two cards together can strand opposing creature decks almost entirely.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Commander is where Stormtide Leviathan actually lives — eight mana is acceptable in a 40-life multiplayer format full of ramp and cheat effects, and a global combat lock generates immediate table-warping value against three opponents at once. In Modern and Legacy, it's a legal curiosity at best; eight-mana do-nothings-until-they-attack don't survive long enough in those formats to justify the slot. Pioneer gives it no better a home — the format's threats close games faster than this can lock them. Oathbreaker is theoretically legal but the 20-life clock makes eight mana a practical non-starter without dedicated acceleration.

Price Context

Current price

$0.49 bulk tier

At $0.49, Stormtide Leviathan is deep bulk — easy to acquire and easy to throw in any sea-monster pile without thinking twice about the cost. Don't expect that to change; it's been widely printed and demand stays flat outside its dedicated tribal homes.
