Carte Magic Three Tree Mascot

Three Tree Mascot 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.) {1}: Add one mana of any color. Activate only once each turn.

Complete guide

Three Tree Mascot is a versatile Artifact Creature that serves as the ultimate glue for tribal decks and mana fixing. Thanks to its Changeling ability, it fits perfectly into any strategy that cares about specific creature types while helping you cast spells of any color.

One Mascot, Every Type

The core feature of Three Tree Mascot is Changeling. This is a characteristic-defining ability that works in all zones, including the library, graveyard, and even on the stack. Because it is every creature type at once, it counts as a Mouse, a Squirrel, a Dragon, and everything in between for any card effect that checks for a type.

Filtering Your Mana

Beyond its identity as a Shapeshifter, the Mascot acts as a mana filter. By paying one generic mana, you can produce one mana of any color. It is important to note that this is an activated ability that can only be used once per turn, meaning you cannot use it to filter multiple mana on the same turn to cast expensive multicolored spells.

Type Overwriting and Ability Loss

A common point of confusion involves effects that change types or remove abilities. If an effect turns the Mascot into a specific type, like a Frog, it loses all other types but keeps the Changeling ability. Conversely, if an effect causes the Mascot to lose all abilities, it remains all creature types. This is because Changeling is applied in a lower layer of the game rules than ability-removal effects.

Interaction examples

Reducing the Cost

If you have Foundry Inspector on the battlefield, the cost to cast Three Tree Mascot is reduced by {1}. You only need to pay {1} generic mana to put the Mascot onto the battlefield, making it a very efficient way to trigger creature-type synergies early in the game.

Mana Coordination

While Ornithopter of Paradise can tap to add one mana of any color for free, Three Tree Mascot requires an investment of {1} generic mana. If you have both, you can tap the Ornithopter for a color you need, and then use a generic mana from another source to activate the Mascot's ability, effectively giving you two mana of any specific colors to cast your spells.

How it works : Three Tree Mascot

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    Changeling is a characteristic-defining ability. It functions in all zones, not only while a card that has it is on the battlefield.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    The subtype Shapeshifter that appears on the type line is mostly there to reinforce the flavor. A creature card with changeling is just as much a Mouse, a Frog, a Rabbit, a Lizard, and a Brushwagg as it is a Shapeshifter.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    If an effect causes a creature with changeling to become a new creature type, it will be only that new creature type. It will still have changeling; the effect making it all creature types will simply be overwritten.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    If an effect causes a creature with changeling to lose all abilities, it will remain all creature types, even though it will no longer have changeling. This is because changeling applies before the effect that removes it.

    No other card is named in this ruling.
