Carte Magic Obuun, Mul Daya Ancestor

Obuun, Mul Daya Ancestor 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

At the beginning of combat on your turn, up to one target land you control becomes an X/X Elemental creature with trample and haste until end of turn, where X is Obuun's power. It's still a land. Landfall — Whenever a land you control enters, put a +1/+1 counter on target creature.

How it works : Obuun, Mul Daya Ancestor

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    A landfall ability triggers whenever a land you control enters for any reason. It triggers whenever you play a land, as well as whenever a spell or ability puts a land onto the battlefield under your control.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    A landfall ability doesn't trigger if a permanent already on the battlefield becomes a land.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    Whenever a land you control enters, each landfall ability of the permanents you control will trigger. You can put them   on the stack in any order. The last ability you put on the stack will be the first one to resolve (As a result, you can have those abilities resolve in the order of your choosing.).

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    Obuun's first ability doesn't remove any abilities the land creature has.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    Obuun's first ability can target a land that's already a creature. This overwrites any previous effects that set the land creature's power and/or toughness to specific values. Other effects that set these characteristics to specific values that start to apply after the ability resolves will overwrite that part of the effect.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    Effects that modify the power or toughness of the land creature without setting it will apply to its new base power and toughness no matter when they started to take effect. The same is true for counters that change its power and toughness.

    No other card is named in this ruling.
