As this enchantment enters, choose a creature type. Creatures you control are the chosen type in addition to their other types. The same is true for creature spells you control and creature cards you own that aren't on the battlefield.

Card Rulings
- January 19, 2018
To choose a creature type, you must choose an existing creature type, such as Vampire or Knight. You can’t choose multiple creature types, such as “Vampire Knight.” Card types such as artifact can’t be chosen, nor can subtypes that aren’t creature types, such as Jace, Vehicle, or Treasure.

Replacement effects that modify creatures of a certain type as they enter the battlefield will apply after you apply Arcane Adaptation’s effect. This is a change from previous rules. If you control Arcane Adaptation and the Aether Revolt card Metallic Mimic, with the same creature type chosen for both, then any creature you control will enter the battlefield with an additional +1/+1 counter on it.

Price History

To study a single card is to glimpse the heart of a spell - a frozen moment of ambition, artistry, and arcane intent. Within each glyph lies a spark: a story untold, a duel turned, a destiny altered. Treat it not as mere parchment, dear seeker, but as a shard of the Multiverse itself.
