Carte Magic Test of Faith

Test of Faith 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

Prevent the next 3 damage that would be dealt to target creature this turn. For each 1 damage prevented this way, put a +1/+1 counter on that creature.

Complete guide

Test of Faith is a versatile white instant that transforms incoming damage into a permanent strength boost for your creatures. It serves as both a protective shield and a combat trick, ensuring your favorite threat survives a lethal blow while growing even larger in the process.

What It Does

Test of Faith creates a prevention shield that lasts until the end of the turn or until it has prevented 3 total damage. When that damage would be dealt, the spell steps in to stop it and immediately places a +1/+1 counter on the creature for every 1 damage prevented. This effect happens simultaneously, meaning the creature grows at the exact moment it would have been hurt.

How It Resolves Step by Step

First, you cast the spell targeting a creature you control. Once it resolves, a 'shield' is placed on that creature. The next time damage would be dealt to that creature this turn—whether from combat, a spell, or an ability—you prevent up to 3 of that damage. Finally, you count how much damage was actually prevented and put that many +1/+1 counters on the creature immediately. If more than 3 damage was coming in, the remaining damage is still dealt after the counters are applied.

Common Mistakes

A common misconception is that the creature might die before the counters are added if the damage is high. However, the official rulings clarify that if a 1/1 creature is dealt 6 damage, 3 is prevented and 3 counters are added simultaneously. The creature becomes a 4/4 with 3 damage marked on it, surviving the hit. Also, remember that this only prevents damage; it does not protect against 'destroy' effects or exile effects.

When to Play It

The best time to cast Test of Faith is during the declare blockers step or in response to a damage-based removal spell. Because the counters are permanent, it provides lasting value far beyond the current turn, effectively punishing your opponent for trying to engage in combat or use burn spells.

Interaction examples

Mitigating Combat Damage

If your 2/2 creature is blocked by a 3/3, you cast Test of Faith before damage is dealt. The 3 damage from the blocker is prevented, and your creature receives three +1/+1 counters, becoming a 5/5. It survives the combat, and your opponent's creature is destroyed by your creature's 5 power.

Synergy with Life Gain

If your opponent targets your creature with a damage spell, you can respond with Test of Faith to add three +1/+1 counters. If you then cast Swords to Plowshares on your own creature in response to a different threat later, you will gain more life because the creature's power was permanently increased by those counters.

Handling Exile Effects

If an opponent casts Path to Exile on your creature, casting Test of Faith will not save it. Test of Faith only interacts with damage. Since Path to Exile exiles the creature without dealing damage, the prevention shield will remain unused, and the creature will be removed from the battlefield.

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    The +1/+1 counters are put onto the creature at the same time the damage is prevented. If a 1/1 creature would be dealt 6 damage, 3 damage is prevented and three +1/+1 counters are put on the creature. The creature ends up as a 4/4 creature with 3 damage marked on it.
