"Find me cards equivalent to: Mordenkainen's Polymorph"

Equivalent cards in blue ('U') with similar effects (temporarily changing a creature's type or stats) are:

  • Polymorphist's Jest: Until end of turn, creatures target player controls become 1/1 blue Frogs with no abilities.
  • Turn to Frog: Until end of turn, target creature becomes a 1/1 blue Frog and loses all abilities.
  • Sudden Spoiling (not blue, but a close effect in black).

All are instants and temporarily change type/stats. Your reference: Mordenkainen's Polymorph. No direct equivalent that makes a creature a Dragon, but same concept.

  • The creature doesn't lose any of its abilities.

    Rules

  • 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.

    Abilities/Keywords

    Rules

  • After a spell with split second resolves (or otherwise leaves the stack), players may again cast spells and activate abilities before the next object on the stack resolves.
  • Casting a spell with split second won't affect spells and abilities that are already on the stack.
  • If the resolution of a triggered ability involves casting a spell, that spell can't be cast if a spell with split second is on the stack.
  • Players may turn face-down creatures face up while a spell with split second is on the stack.
  • Players still get priority while a card with split second is on the stack; their options are just limited to mana abilities and certain special actions.
  • Split second doesn't stop triggered abilities from triggering, such as that of Chalice of the Void. If one does, its controller puts it on the stack and chooses targets for it, if any. Those abilities will resolve as normal.
  • Sudden Spoiling affects only creatures the target player controls at the time it resolves. Creatures they begin to control later in the turn won't change power and toughness or lose abilities.
  • Sudden Spoiling overwrites any effects that set a creature's power and toughness. Any existing effects or counters that raise, lower, or switch a creature's power and/or toughness continue to apply to the creature's newly-set power and toughness.
