Carte Magic Chamber Sentry

Chamber Sentry 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

This creature enters with a +1/+1 counter on it for each color of mana spent to cast it. {X}, {T}, Remove X +1/+1 counters from this creature: It deals X damage to any target. {W}{U}{B}{R}{G}: Return this card from your graveyard to your hand.

How it works : Chamber Sentry

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    You can choose any value for X as you cast Chamber Sentry. The value chosen for X doesn't directly affect the number of +1/+1 counters Chamber Sentry enters the battlefield with, but it does let you pay more mana and thus spend more colors of mana to cast it.

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    If an effect allows you to spend mana as though it were mana of any color to cast Chamber Sentry, you consider only the actual mana spent to determine how many counters it receives.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    Colorless mana won't give Chamber Sentry another +1/+1 counter. Colorless is not a color.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    If Chamber Sentry enters the battlefield without being cast, it receives no +1/+1 counters.

    No other card is named in this ruling.

  5. #5· Wizards of the Coast

    If another creature enters the battlefield as a copy of Chamber Sentry, consider what mana was spent to cast that creature to determine how many +1/+1 counters it enters with.

    No other card is named in this ruling.

  6. #6· Wizards of the Coast

    The value of X chosen when you activate Chamber Sentry's first activated ability doesn't have to be the same value of X that you chose when you cast it.

    No other card is named in this ruling.
