Kamahl's SledgeHow it works & interactions with other cards

What It Does

At its base level, Kamahl's Sledge deals 4 damage to a single target creature for seven mana. However, the card features the Threshold keyword, a static ability that checks if you have seven or more cards in your graveyard as the spell resolves. If you meet this requirement, the spell's effect is replaced, dealing 4 damage to both the creature and its controller simultaneously.

How It Resolves Step by Step

When you cast the spell, you must choose a target creature. As Kamahl's Sledge resolves, the game checks your graveyard count. If you have six or fewer cards, the creature takes 4 damage and the spell is finished. If you have seven or more cards, the 'instead' clause kicks in: the creature is dealt 4 damage, and the player who controls that creature is also dealt 4 damage. Note that if the creature becomes an illegal target before resolution, the entire spell fails and no damage is dealt to anyone.

Common Mistakes

The most common error is miscalculating the graveyard count. Kamahl's Sledge is on the stack while it is resolving, not in the graveyard, so it does not count toward its own Threshold requirement. Additionally, players often forget that the damage to the player is dependent on the creature being a legal target; you cannot target a player directly with this spell.

When to Play It

This card is most effective in decks that can quickly fill the graveyard through discarding or milling. Because it costs seven mana, it is often a late-game finisher. Use it when you need to remove a problematic blocker while simultaneously pressuring your opponent's life total to close out the match.

Interaction examples

Reaching Threshold Early

All Is Dust

If you have five cards in your graveyard and cast All Is Dust, you may sacrifice several colored permanents. Once those permanents enter the graveyard, your graveyard count will likely exceed seven. When you later cast Kamahl's Sledge, it will detect these new cards and trigger the Threshold effect to damage both a creature and its controller.

The Importance of Legal Targets

Full Throttle

If you cast Kamahl's Sledge targeting a creature, and your opponent somehow removes that creature from the battlefield in response (even if you have Threshold), the spell will have no legal targets. In this scenario, no damage is dealt to the creature's controller, even if you were planning to use Full Throttle later to gain extra combat phases.
