"Find me cards equivalent to: Reverse the Polarity"

Equivalent or similar cards to Reverse the Polarity in blue (U), Instant speed, sharing at least some effects:
1. Polymorphist's Jest – Turns creatures into 1/1s, as a blue instant with unusual creature effects.
2. Aetherize – Returns all attacking creatures to owners’ hands, as a blue instant for defensive purposes.
3. Turnabout – Allows you to choose to untap/tap all creatures or lands of a type, flexibility in modes.
4. Turn to Frog – Instant that changes a creature’s stats (effect like switching power/toughness).
5. Inundate – Not an instant, but a blue spell that returns certain creatures to hand, fitting disruptive blue.
6. Aetherize and Aetherspouts – Blue instants for large board impact.

While none does every listed mode, Polymorphist's Jest and Aetherize are closest blue instants for big board effects; Turnabout is closest for modal design. No mono-blue instant directly has all three effects like Reverse the Polarity.

  • An "attacking creature" is one that has been declared as an attacker this combat, or one that was put onto the battlefield attacking this combat. Unless that creature leaves combat, it continues to be an attacking creature through the end of combat step, even if the player it was attacking has left the game, or the planeswalker it was attacking has left combat. There's no such thing as an attacking creature outside of the combat phase.

  • If an effect puts two or more cards on the top or bottom of a library at the same time, the owner of those cards may arrange them in any order. That library's owner doesn't reveal the order in which the cards go into their library.
  • The owner of each attacking creature chooses whether to put it on the top or bottom of their library. The active player (the player whose turn it is) makes all of their choices first, followed by each other player in turn order.

  • Creatures that enter the battlefield or come under the target player’s control after Polymorphist’s Jest resolves won’t be affected.
  • Effects that modify a creature’s power and/or toughness, such as the effect of Titanic Growth, will apply to the creatures no matter when they started to take effect. The same is true for any counters that change their power and/or toughness and effects that switch power and toughness.
  • If one of the Theros block Gods is affected by Polymorphist’s Jest, it will be a legendary 1/1 blue Frog enchantment creature with no abilities. If it stops being a creature, perhaps because your devotion to its color(s) decreased, it will be a legendary blue enchantment with no abilities. The way continuous effects work, the God’s type-changing ability is applied before the effect that removes that ability is applied.
  • If one of the affected creatures gains an ability after Polymorphist’s Jest resolves, it will keep that ability.
  • Polymorphist’s Jest doesn’t counter abilities that have already triggered or been activated. In particular, there is no way to cast this spell to stop a creature’s ability that says “At the beginning of your upkeep,” “When this creature enters the battlefield,” or similar from triggering.
  • Polymorphist’s Jest overwrites all previous effects that set the creatures’ base power and toughness to specific values. Any power- or toughness-setting effects that start to apply after Polymorphist’s Jest resolves will overwrite this effect.
  • The creatures will lose all other colors and creature types, but they will retain any other card types (such as artifact) or supertypes (such as legendary) they may have.

  • Because damage remains marked on a creature until the cleanup step or an effect removes that damage, nonlethal damage dealt to a creature may become lethal if you switch its power and toughness during that turn.
  • Effects that switch a creature's power and toughness apply after all other effects, regardless of when those effects began to apply. For instance, if you switch a 2/4 creature's power and toughness and then give it +2/+0 later in the turn, it's a 4/4 creature, not a 6/2 creature.
