Twisted Imageutility$0.23This is the closest functional match: a cheap cantrip that switches a creature’s power and toughness at instant speed. It also targets a creature and replaces itself with a card draw.
Slip Through Spaceutility$11.23A low-cost blue cantrip that helps a creature connect, similar to Inside Out’s pump/combat-trick usage in spell-based decks. It doesn’t swap stats, but it serves a comparable role as a cheap combat enabler that replaces itself.
Psychotic Furyutility$1.04A similar blue-red combat trick that cantrip-draws and boosts a creature’s combat damage output. It works in many of the same aggressive or combo shells, especially with multicolor creatures.
Defiant Strikeutility$0.09A very cheap cantrip combat trick that increases a creature’s damage output and replaces itself. It’s not a stat-swap effect, but it fills a similar slot in spell-heavy aggressive decks.
Shelterprotection$4.84A low-cost cantrip trick that protects a creature while drawing a card, serving a similar tempo-focused role. It’s not a power/toughness swap, but it is an efficient one-mana combat spell in the same color family.
Samut's Sprintutility$0.09A cheap red combat trick that increases a creature’s combat effectiveness and draws a card. It occupies a similar deck slot as a cantripping tempo spell in aggressive lists.
Expediteutility$1.23Another one-mana cantrip that pushes a creature for combat and replaces itself. It’s a budget-friendly equivalent for decks wanting cheap spell density and card flow.
Might of the Massesutility$0.09A one-mana pump spell with cantrip-like efficiency in creature-heavy decks when a simple damage boost is enough. It’s not a swap effect, but it serves the same aggressive-combat-trick function.
