Temur Battlecrier 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

During your turn, spells you cast cost less to cast for each creature you control with power 4 or greater.

Complete guide

Temur Battlecrier is a powerful enabler for mid-range and heavy-hitting decks, rewarding you for maintaining a board of formidable creatures. By reducing the mana cost of your spells, this Orc Ranger allows you to chain multiple threats together in a single turn. Understanding how its cost-reduction ability interacts with your board state is key to maximizing its potential during your combat-focused turns.

Unpacking the Cost Reduction

Temur Battlecrier features a static ability that applies only during your turn. It counts the number of creatures you control with power 4 or greater at the moment you are casting a spell. For each creature meeting this requirement, the generic mana component of your spells is reduced by {1}. Note that this ability cannot reduce the colored mana requirements of a spell; it only applies to the generic mana portion of the total cost.

Step-by-Step Resolution

When you begin the process of casting a spell, the game checks the current state of your battlefield to determine the total cost. First, you announce the spell and any choices like targets. Next, you calculate the cost: start with the mana cost or alternative cost, add any cost increases, and then apply cost reductions like the one from Temur Battlecrier. Once the final cost is determined, it becomes locked in, and you pay that amount. If a creature's power changes after this point, it will not affect the cost of the spell already on the stack.

Strategic Timing and Common Mistakes

A common mistake is assuming Temur Battlecrier reduces its own cost; however, its ability only functions while it is on the battlefield. Therefore, it will not reduce its own casting cost. Additionally, remember that the reduction only checks for power 4 or greater. If a creature's power is temporarily boosted by an instant or an aura to reach 4, it will contribute to the discount. Conversely, if an opponent shrinks your creatures in response to you moving to your main phase, you might lose your discount before you get the chance to cast your next spell.

Interaction examples

Powering Out the Sad Robot

Solemn Simulacrum

With Temur Battlecrier and a creature with 4 power on the battlefield, you decide to cast Solemn Simulacrum during your turn. The game checks your creatures and sees one creature with power 4 or greater. The cost of Solemn Simulacrum is reduced from {4} to {3}. You pay the {3} mana, the Golem enters the battlefield, and you search for a basic land.

Sakura-Tribe Elder

If you control Temur Battlecrier and two creatures with power 4 or greater, any spell you cast during your turn costs {2} less. If you cast Sakura-Tribe Elder, which costs {1}{G}, the {2} reduction applies to the {1} generic mana. The cost is reduced as much as possible, leaving only the {G} requirement. You pay {G} to cast the Elder.
