Strixhaven: School of Mages

Show of Confidence | Instant | | When you cast this spell, copy it for each other instant and sorcery spell you've cast this turn. You may choose new targets for the copies. Put a +1/+1 counter on target creature. It gains vigilance until end of turn. | Paul Scott Canavan

Test of Talents | Instant | | Counter target instant or sorcery spell. Search its controller's graveyard, hand, and library for any number of cards with the same name as that spell and exile them. That player shuffles, then draws a card for each card exiled from their hand this way. | Lie Setiawan

Flunk | Instant | | Target creature gets -X/-X until end of turn, where X is 7 minus the number of cards in that creature's controller's hand. | Randy Vargas

Plumb the Forbidden | Instant | | As an additional cost to cast this spell, you may sacrifice one or more creatures. When you do, copy this spell for each creature sacrificed this way. You draw a card and you lose 1 life. | Andrey Kuzinskiy

Fracture | Instant | | Destroy target artifact, enchantment, or planeswalker. | Miranda Meeks

Decisive Denial | Instant | | Choose one — • Target creature you control fights target creature you don't control. (Each deals damage equal to its power to the other.) • Counter target noncreature spell unless its controller pays {3}. | Lorenzo Mastroianni

Tend the Pests | Instant | | As an additional cost to cast this spell, sacrifice a creature. Create X 1/1 black and green Pest creature tokens with "When this creature dies, you gain 1 life," where X is the sacrificed creature's power. | David Auden Nash
