Opposition card art
Opposition locks opponents out of combat and activated abilities while you untap freely — the board control it creates is immediate and punishing. Hylda of the Icy Crown is the premier home, since every tap trigger feeds Hylda's ability and every Hylda token feeds Opposition right back.

Hylda of the Icy Crown

Hylda of the Icy Crown

74.7% of decks · synergy 0.71

Hylda of the Icy Crown and Opposition form a self-reinforcing loop: Opposition taps down threats and utility creatures, each tap proc fires Hylda's trigger to generate tokens or draw cards, and those tokens become fresh tap fodder for Opposition the following turn.

02
The Watcher in the Water

The Watcher in the Water

18.0% of decks · synergy 0.17

The Watcher in the Water generates Tentacle tokens whenever you tap creatures, which means Opposition doesn't just lock the board — it also engines out a wide army that can tap down even more permanents.

03
Archelos, Lagoon Mystic

Archelos, Lagoon Mystic

15.5% of decks · synergy 0.15

Archelos, Lagoon Mystic enters tapped to slow every opponent's permanent development, and Opposition extends that soft-lock into combat and mana by tapping down whatever slips through, making the combination functionally suffocating for creature-reliant tables.

pauper not legal
oathbreaker legal

Opposition is legal in Commander, Legacy, Vintage, and Oathbreaker, and Commander is where it sees the most play — a table of three opponents means three times the permanents to tap, and the enchantment's symmetry-breaking effect compounds fast in a multiplayer environment. In Legacy it has theoretical homes in creature-heavy blue-green shells, but the format's speed means Opposition rarely resolves before the game ends or gets countered; it simply isn't competitive there. Vintage is technically legal but the power ceiling means Opposition is too slow and too reliant on a board state to compete. Oathbreaker is worth a mention for the same reasons Commander is: multiple opponents, longer games, and decks built around a specific planeswalker that often generate the token or creature density needed to make Opposition immediately threatening.

Price Context

Current price

unknown tier

Current pricing data for Opposition isn't available in this listing, so check Scryfall or TCGPlayer for the most accurate figure — it has historically fluctuated based on reprint availability and has appeared in multiple sets. Given that it's a four-mana enchantment with no competitive presence outside Commander, the price tends to reflect Commander demand alone, which keeps it accessible relative to blue staples of similar power.
