Phyrexian RevokerHow it works & interactions with other cards

What It Does

Phyrexian Revoker prevents players from activating abilities of a chosen nonland card name. An activated ability is always written in the form "Cost: Effect," featuring a colon. This restriction applies to sources in any zone, meaning it stops abilities that trigger from the hand, like cycling, or from the graveyard, as long as they are activated abilities.

How It Resolves Step by Step

First, as Phyrexian Revoker enters the battlefield, you choose a nonland card name; this choice does not use the stack and cannot be responded to once the creature begins to enter. Second, the continuous effect begins immediately, preventing any player from activating abilities of sources with that name. Finally, the effect remains active as long as Phyrexian Revoker stays on the battlefield.

Common Mistakes

The most common error is trying to name a land card; since the text specifies 'nonland card name,' you cannot name cards like basic lands or utility lands. Additionally, remember that Phyrexian Revoker only stops activated abilities. It does not stop triggered abilities (which use 'when,' 'whenever,' or 'at') or static abilities that modify costs or rules of the game.

When to Play It

Phyrexian Revoker is best played when you identify a specific card that your opponent relies on for utility or mana. Because it is a creature, it can be easily tutored or recurred, making it a flexible hate piece in many aggressive or midrange artifact strategies.

Interaction examples

Silencing the Thopter

Ornithopter of Paradise

If you play Phyrexian Revoker and name Ornithopter of Paradise, your opponent can no longer activate the ability '{T}: Add one mana of any color.' Even though this is a mana ability, Phyrexian Revoker explicitly stops it because the source is a nonland card. The Ornithopter can still fly and block, but it cannot produce mana.

The Limit of Revocation

Foundry Inspector

If you name Foundry Inspector with Phyrexian Revoker, nothing changes. This is because Foundry Inspector's ability to reduce the cost of artifact spells is a static ability, not an activated ability. There is no colon in its text, so Phyrexian Revoker has no effect on its function.
