Party Thrasher
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.

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.
Multiple instances of convoke on a single spell are redundant.
When using convoke to cast a spell with
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 
) from exile, choosing 3 as the value of X, the total cost is 
. If you tap a white creature and a red creature, you'll have to pay 
.If a creature you control has a mana ability with
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.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.
Because convoke isn't an alternative cost, it can be used in conjunction with alternative costs.
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.
