Rhystic CircleHow it works & interactions with other cards

What It Does

Rhystic Circle provides a repeatable activated ability that targets a source of damage. For one generic mana, you create a prevention shield that triggers unless a player chooses to pay an additional mana. It is important to note that this only protects you, the player, and cannot be used to save your creatures or planeswalkers from damage.

How It Resolves Step by Step

First, you pay {1} to activate the ability and choose a source of damage, such as a specific creature or a spell on the stack. Next, as the ability resolves, every player (including you, though unlikely) has the opportunity to pay {1}. If no one pays, the prevention shield is established. The next time that specific source would deal damage to you this turn, that damage is reduced to zero.

Common Mistakes

A frequent error is trying to activate the ability after damage has already been dealt; you must activate this before the damage event occurs. Additionally, remember that Rhystic Circle does not stop 'loss of life' effects, only damage. Finally, because the choice to pay happens during resolution, you cannot wait to see if a player pays before deciding to activate it multiple times for the same source.

When to Play It

This card shines in political multiplayer formats like Commander where you have excess mana. It functions as a deterrent, as opponents are often unwilling to pay the 'tax' to damage you when they could simply attack someone else. It is especially effective against decks that rely on a single large source of damage rather than many small ones.

Interaction examples

Taxing the Attack

Ghostly Prison

With Ghostly Prison on the battlefield, your opponent must pay {2} just to declare an attacker. Once they attack, you can activate Rhystic Circle for {1}. The opponent must then pay another {1} or their creature's damage will be prevented, making it incredibly expensive for them to successfully hit you.

Mana Advantage Taxes

Smothering Tithe

Smothering Tithe helps you generate Treasure tokens whenever your opponents draw cards. You can use these Treasures to fuel multiple activations of Rhystic Circle, effectively using your opponents' own card draw to fund the prevention of any damage they try to send your way.

Choosing a Source

If an opponent casts a spell that deals damage to you, you activate Rhystic Circle in response. You choose the spell as the source. If the opponent chooses not to pay {1} during the resolution of the Circle's ability, the spell will deal no damage to you when it eventually resolves.
