Carte Magic Carth the Lion

Carth the Lion 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

Whenever Carth enters or a planeswalker you control dies, look at the top seven cards of your library. You may reveal a planeswalker card from among them and put it into your hand. Put the rest on the bottom of your library in a random order. Planeswalkers' loyalty abilities you activate cost an additional [+1] to activate.

How it works : Carth the Lion

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    If a planeswalker's loyalty ability normally has a cost of [+1], Carth's ability makes it cost [+2] instead. A cost of [0] would become [+1], and a cost of [-6] would become [-5].

    No other card is named in this ruling.

  2. #2· Wizards of the Coast

    If you somehow manage to control two Carths (perhaps because of Spark Double), the cost-changing effect is cumulative. In total, loyalty abilities will cost an additional [+2] to activate.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    The total cost of a planeswalker's loyalty ability is calculated before any counters are added or removed. If a loyalty ability normally costs [-3] to activate, you do not remove three counters from it and then put one counter on it. You remove two counters at one time when you pay the cost.

    No other card is named in this ruling.

  4. #4· Wizards of the Coast

    If an effect replaces the number of counters that would be placed on a planeswalker, such as that of Vorinclex, Monstrous Raider, that replacement happens only once, at the time payment is made.

    No other card is named in this ruling.
