Sphere of SafetyHow it works & interactions with other cards

How the Taxation Works

Sphere of Safety creates a static ability that imposes a cost on the act of declaring attackers. For every single creature an opponent wants to send your way, they must pay {X}, where X is the total number of enchantments you control at the moment attackers are declared. This includes Sphere of Safety itself, meaning the tax is at least {1} as long as this card is on the battlefield.

Step-by-Step Resolution

First, the active player enters the Declare Attackers step. Before any creatures are officially tapped or declared, the player must determine if they can pay the costs. They count your enchantments, multiply that by the number of creatures they wish to attack with, and then activate mana abilities to pay this total. If they cannot or choose not to pay for a specific creature, that creature cannot be declared as an attacker.

Common Strategic Mistakes

A common misconception is that this tax applies to creatures 'put onto the battlefield attacking.' It does not; the tax only applies to creatures declared as attackers during the turn-based action. Additionally, if you control a creature that 'attacks if able,' Sphere of Safety provides an out. Official rulings state that if the controller cannot or will not pay the {X}, the 'if able' condition is not met, and the creature simply doesn't attack.

When to Deploy Your Sphere

The best time to play Sphere of Safety is once you have established a few other enchantments to ensure the tax is high enough to be disruptive. Since it counts itself, even a small board makes attacking difficult. It is particularly effective against 'Go Wide' strategies that rely on many small creatures, as the cumulative cost becomes impossible to pay.

Interaction examples

Multiplying the Tax

Anointed Procession

With both Sphere of Safety and Anointed Procession on the battlefield, you control two enchantments. If an opponent wants to attack you with three creatures, they must pay {2} for each creature, totaling {6}. If you later create a token and Anointed Procession creates two instead, your enchantment count doesn't change unless those tokens are also enchantments.

The Tithe Fortress

Smothering Tithe

When you control both Sphere of Safety and Smothering Tithe, your opponent faces a double mana bind. Smothering Tithe pressures their mana during their draw step, and Sphere of Safety pressures their mana during their combat phase. If they spend mana to stop you from getting Treasures, they likely won't have enough left to pay the {X} tax required to attack you.

Solo Defense

If Sphere of Safety is the only enchantment you control, X equals 1. An opponent with five 1/1 soldier tokens would need to pay {5} to attack with all of them. If they only have {2} available, they can only choose two soldiers to attack with, while the other three must stay back.
