Carte Magic Amoeboid Changeling

Amoeboid Changeling is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

01

Official card text

Changeling (This card is every creature type.) {T}: Target creature gains all creature types until end of turn. {T}: Target creature loses all creature types until end of turn.

Complete guide

Amoeboid Changeling is a versatile blue creature that embodies every creature type at once. Its ability to grant or strip creature identities makes it a unique tool for tribal strategies and disruptive plays alike.

What it does

Amoeboid Changeling features the Changeling keyword, meaning it is always every creature type, including Elf, Sliver, and even Brushwagg. It has two activated abilities that require tapping it: one to grant all creature types to another creature, and one to remove all creature types from another creature until the end of the turn.

How it resolves step by step

When you activate the first ability, you choose a target creature; upon resolution, that creature gains every possible creature type in Magic. When you activate the second ability, the targeted creature loses all its existing creature types, becoming 'typeless.' If a creature that has lost its types gains a new one later in the same turn via a different effect, it will have only that new creature type.

Common Mistakes

A common misconception is that losing creature types also causes a creature to lose its abilities or its status as a creature. Using the second ability on a creature does not stop it from being a creature, nor does it remove keywords like Flying or Ward. It simply removes the labels like 'Human' or 'Soldier' from the type line.

When to play it

This card is best used in decks that rely on specific creature types to function. You can use it to make a non-tribal creature benefit from tribal lords, or use it defensively to break an opponent's tribal synergies by stripping their creature of its necessary types.

Interaction examples

Typeless Artifacts

If you target Ornithopter of Paradise with Amoeboid Changeling's second ability, the Ornithopter loses the 'Thopter' creature type. It remains an Artifact Creature and keeps its Flying and mana-production abilities, but it no longer counts as a Thopter for any effects that check for that type.

Cost Reduction Identity

By using the first ability on Foundry Inspector, you make it every creature type. While this doesn't change its own cost-reduction effect (which checks for the 'Artifact' type), it now qualifies for any tribal buffs on your battlefield, such as those that give +1/+1 to Slivers or Goblins.
