What is the Mutate Cost?
Defining Mutate Costs
In Magic: The Gathering, Mutate is an alternative casting cost for creatures that allows you to modify the creature’s original casting cost. In simple terms, the Mutate cost refers to the alternative cost stated in a creature’s rules text. This cost replaces the creature’s original mana cost, allowing you to cast it using the alternative cost. Here are some key points to note:
- The mutate cost is a part of the creature’s text.
- It is only accessible if you choose to use mutate instead of paying the original mana cost.
- Once the mutate cost is used, the creature can be cast using the new, alternative cost.
Paying the Mutate Cost
When you use Mutate, you need to pay the alternative casting cost. This cost may differ from the creature’s original mana cost. Keep the following points in mind:
- You can’t pay the mutate cost without the mutate ability.
- The mutate ability does not change the mana symbols on the spell, but rather replaces them.
- Any other additional costs or considerations associated with the original mana cost are still applicable when paying the mutate cost.
Examples of Mutate Costs
Let’s explore some examples to help you better understand the Mutate cost:
| Creatures | Mutate Cost |
|---|---|
| Cloudpiercer ( creature – Flying ) | You may pay an alternative, nonmana cost: reveal the top card of your library. Then cast it without paying its mana cost. |
| Miren, Keeper of Thieves ( creature ) | You may pay an alternative, nonmana cost: you may return two mana artifacts from your graveyard to the battlefield under their original controller’s control. |
| Hellrider | You may pay an alternative, nonmana cost: destroy two creatures with different names. |
In the first example, you need to reveal the top card of your library to use the mutate cost of Cloudpiercer. This new cost replaces the creature’s original mana cost, which is likely more difficult to pay.
In the second example, Miren, Keeper of Thieves, allows you to use a mutate cost to return two mana artifacts from your graveyard to the battlefield under the original controller’s control. This is an unconventional, non-mana alternative to the creature’s original casting cost.
The Hellrider example requires you to destroy two creatures with different names to use its mutate cost. This alternate casting cost replaces the original mana cost, adding another layer of strategy to gameplay.
Implications for CMC and Legend Rules
When using a Mutate cost, remember:
- Mana Cost and CMC: Although you pay an alternative, non-mana cost using the Mutate ability, Mana Cost and Converted Mana Cost (CMC) still play a role. Moreso, some game states, such as creating an illegal game state due to an over-mana value, still affect games involving Mutate.
