Mardu Runemark 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.
Official card text
Enchant creature Enchanted creature gets +2/+2. Enchanted creature has first strike as long as you control a white or black permanent.
Complete guide
Mardu Runemark is an aggressive Aura that bolsters your creature's combat prowess based on the colors of your board state. By rewarding you for branching into white or black, it turns any simple creature into a formidable warrior. Let's break down how this red enchantment interacts with your team and the timing of its abilities.
A Drastic Power Boost
Mardu Runemark provides a static +2/+2 bonus to the creature it enchants. This increase is always active as long as the Aura is attached, regardless of other permanents you control. However, the second part of the ability is conditional; the creature gains first strike only if you control at least one white or black permanent.
How it Resolves Step by Step
When you cast Mardu Runemark, you must choose a creature as a target. If the spell resolves, it enters the battlefield attached to that creature. Once on the board, the game constantly checks if you control a white or black permanent. If you do, the enchanted creature immediately has first strike. If you lose all white and black permanents, the creature loses first strike instantly.
Timing and Combat Steps
First strike creates an additional combat damage step. If your creature has first strike during the first damage step, it deals damage then. A common mistake involves losing the requirement mid-combat. If the creature deals damage in the first strike step and then loses the ability before the normal damage step, it does not get to deal damage a second time.
Strategy: When to Cast
This card is best used when you already have a established board presence of white or black permanents to ensure your creature can win combat without taking damage. Because it is an Aura, be wary of your opponent's removal spells, as losing the creature results in losing the Runemark as well.
Interaction examples
You control a creature enchanted with Mardu Runemark and Impact Tremors. Since Impact Tremors is a red permanent and not white or black, the enchanted creature receives +2/+2 but does not have first strike. To gain first strike, you would need to play a white or black permanent, such as a white creature or a black enchantment.
If Mardu Runemark is in your graveyard and you control Underworld Breach, you can cast the Aura for its escape cost. Once it enters the battlefield and attaches to a creature, it provides +2/+2. Because Underworld Breach is a red permanent, it still does not grant the first strike bonus. You must ensure at least one white or black permanent is on your side of the battlefield for the second ability to be active.
