Is Sunderflock good in Commander?

Sunderflock in Commander — Combos, Decks & Price

Sunderflock bounces all creatures — yours included — at instant speed, which is a sweeper, a protection spell, and a reset button depending on when you cast it. The cost is real: you lose your own board too, so it rewards decks that either rebuild faster than opponents or already have what they need in the command zone.

Best Commanders

Commanders with the highest synergy

01

Ashling, the Limitless

67.2% of decks · synergy 0.60

Ashling, the Limitless recasts herself from the command zone after Sunderflock clears the board, meaning you get a clean slate while opponents do not — it's a one-sided reset in everything but the rules text. Two-thirds of Ashling decks run it for exactly that reason.

02

Omnath, Locus of the Roil

43.1% of decks · synergy 0.42

Omnath, Locus of the Roil triggers on Elementals entering the battlefield, so Sunderflock bouncing your board sets up a mass re-entry of Elementals for a fresh wave of damage and draw. It pairs especially well with cheap Elementals that flood back onto the field in a single turn.

03

Eris, Roar of the Storm

24.8% of decks · synergy 0.24

Eris, Roar of the Storm cares about casting spells and putting Bird tokens into play, so Sunderflock creates an immediate recast engine — bounce your tokens, then rebuild the flock with every spell you play. About a quarter of Eris decks include it as a recoverable pseudo-wipe.

04

Ashling, Rekindled

13.7% of decks · synergy 0.13

Ashling, Rekindled benefits from clearing opponents' boards without permanence loss being a death sentence, since she rebuilds naturally through her own abilities. Sunderflock gives that shell a panic button that punishes opponents who overcommit to the board.

Format Analysis

Where it lives, where it can’t

Format	Verdict
commander	legal
legacy	legal
modern	legal
pioneer	legal
standard	legal
vintage	legal
pauper	not legal
oathbreaker	legal

Sunderflock is legal across every major format but lives almost entirely in Commander, where the political and asymmetric value of a full bounce effect is highest. In 1v1 formats like Modern and Pioneer, symmetrical bounce at sorcery speed would be unplayable, and at instant speed it still asks you to rebuild alongside your opponent — the math rarely works out. In Commander, the calculus flips: three opponents lose their boards while you execute a plan that doesn't depend on the creatures you just sent back. Oathbreaker is a reasonable home for the same reason Ashling decks love it — commanders with enter-the-battlefield value make the symmetry fake.

Price Context

Current price

$1.92 cheap tier

At $1.92, Sunderflock sits in the cheap tier and represents strong value for what it does — a functional one-sided board reset in the right shell at under two dollars is a deal. It's a card played heavily enough in Ashling decks that demand is real, but not so scarce that the price is likely to spike dramatically.
