Party Thrasher — ruling 1

If you sacrifice Party Thrasher while casting a noncreature spell from exile (to activate a mana ability, for example), the spell won't have convoke when you pay its costs unless it has convoke some other way.

Party Thrasher — ruling 2

Multiple instances of convoke on a single spell are redundant.

Party Thrasher — ruling 3

When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated. Convoke doesn't change a spell's mana cost or mana value.

Party Thrasher — ruling 4

If a creature you control has a mana ability with {T} in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.

Party Thrasher — ruling 5

Because convoke isn't an alternative cost, it can be used in conjunction with alternative costs.

Party Thrasher — ruling 6

When using convoke to cast a spell with {X} in its cost, first choose the value for X. That choice, plus any cost increases or decreases, will determine the spell's total cost. Then you can tap creatures you control to help pay that cost. For example, if you cast Wrath of the Skies (a spell with mana cost {X}{W}{W}) from exile, choosing 3 as the value of X, the total cost is {3}{W}{W}. If you tap a white creature and a red creature, you'll have to pay {2}{W}.

Party Thrasher — ruling 7

You pay all costs and follow all normal timing rules for cards played using Party Thrasher's second ability. For example, if the chosen exiled card is a land card, you may play it only during your main phase while the stack is empty.

Party Thrasher : règles, fonctionnement et interactions (MTG)

Party Thrasher is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Noncreature spells you cast from exile have convoke. (Each creature you tap while casting a noncreature spell from exile pays for or one mana of that creature's color.) At the beginning of your first main phase, you may discard a card. If you do, exile the top two cards of your library, then choose one of them. You may play that card this turn.

Complete guide

Party Thrasher is a vibrant Lizard Wizard that turns your exile zone into an extension of your hand while providing an efficient way to pay for spells. By discarding unwanted resources, you can dig deeper into your library and utilize your creatures to cast noncreature spells found in exile.

Granting Convoke to the Exile Zone

The first ability of Party Thrasher gives noncreature spells you cast from exile the convoke keyword. Convoke allows you to tap your creatures to pay for generic or colored mana in the spell's cost. Importantly, this only applies to noncreature spells, and the spells must be cast specifically from the exile zone to qualify for this benefit.

The First Main Phase Trigger

At the start of your first main phase, you have the option to discard a card. If you do, you exile the top two cards of your library and choose one. You can play that chosen card until the end of the turn. Note that you must follow normal timing rules; if you exile a land, you can only play it during your main phase when the stack is empty, provided you have a land play available.

Cost Calculation and Timing

Convoke is not an alternative cost; it is a method of payment. You first determine the total cost of the spell, including any additional costs or X values. Then, you may tap creatures to pay for that cost. If a creature has a mana ability that requires tapping, like Ornithopter of Paradise, you cannot tap it for its mana ability and then tap it again for convoke for the same spell.

Common Mistakes

A common error is trying to use convoke for creature spells cast from exile; Party Thrasher only grants convoke to noncreature spells. Additionally, if Party Thrasher leaves the battlefield while you are in the middle of casting a spell from exile (for example, by sacrificing it to a mana ability), the spell loses convoke before you reach the payment step unless another effect provides it.

Interaction examples

Thrasher and the Face-Breaker

Professional Face-Breaker

If you sacrifice a Treasure to Professional Face-Breaker's ability and exile a noncreature spell, Party Thrasher grants that spell convoke. You can then tap your creatures, including the Professional Face-Breaker itself, to help pay for the cost of that exiled spell.

Managing Mana Dorks

Ornithopter of Paradise

When casting a noncreature spell from exile, you must choose how to use Ornithopter of Paradise. You can either tap it for its mana ability to add one mana of any color, or tap it for convoke to pay for one mana of its color (colorless). You cannot do both for the same spell because the creature becomes tapped during the first action you choose.

Filtering for Action

At the start of your first main phase, you discard a redundant land card from your hand. You exile two cards from your library, choosing a noncreature instant. Even if you don't have enough lands to cast it, you can tap Party Thrasher and your other creatures to pay its mana cost immediately because it now has convoke.
