What it does

At the beginning of combat on your turn, put X +1/+1 counters on each creature you control, where X is this creature's power.

Combos with Ouroboroid

Lines this card is part of — what it needs alongside it, and what the two of them do. An infinite result is the one that moves a deck's bracket.

Combo data from Commander Spellbook, the community-maintained database of Magic combos. Mirrored nightly.

Rulings

2 official rulings, in the order Wizards published them.

  • 2025-07-25

    The value of X is calculated only once, as Ouroboroid’s ability resolves.

  • 2025-07-25

    If Ouroboroid leaves the battlefield before its ability resolves, use its power as it last existed on the battlefield to determine the value of X.

Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Every version of Ouroboroid

4 printings, newest first. Prices are the market figures Scryfall publishes, refreshed nightly — a printing with no figure shows a dash rather than a zero, because Scryfall genuinely publishes none for some of them.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for Ouroboroid — a name search across every version, for the printings TCGplayer publishes no direct link to.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only — no individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
