Does Commander Tax Add to CMC? A Definitive Guide

No, the Commander Tax does NOT add to the Converted Mana Cost (CMC) of your Commander. The Commander Tax is an additional cost you pay when casting your commander from the command zone, while CMC is an attribute of the card itself, printed on the upper right corner (or calculated based on the card’s text if it’s absent). These are entirely separate and should not be confused.

Understanding Converted Mana Cost (CMC)

The Converted Mana Cost (CMC), often just called Mana Value, is the total amount of mana required to cast a card. This value is derived directly from the mana symbols printed in the upper-right corner of the card. For example:

• A card with a mana cost of {2}{W} has a CMC of 3.
• A card with a mana cost of {G}{U}{B} has a CMC of 3.
• A card with a mana cost of {X}{X}{R} has a CMC of 1 + X + X as it enters the stack.
• A card with no mana cost (like lands) has a CMC of 0.

Cards with variable mana costs (containing {X}) have a CMC calculated based on the value chosen for X while on the stack. Everywhere else, the value is determined as if X were 0. This distinction is crucial when effects refer to a card’s CMC, such as countering spells with a specific mana value.

Demystifying Commander Tax

The Commander Tax is an additional cost you pay whenever you cast your commander from the command zone after it has previously been cast and returned there. This tax increases by {2} for each previous time you’ve cast the commander from the command zone in the same game.

Imagine this: you have a commander with a mana cost of {2}{G}{W} (CMC of 4). The first time you cast it from the command zone, you pay 4 mana. The second time, you pay 4 + 2 = 6 mana. The third time, you pay 4 + 2 + 2 = 8 mana, and so on. Crucially, this additional cost doesn’t change the CMC of the card. It only alters the total mana you have to spend when you cast your commander from the command zone.

Why the Distinction Matters

The difference between CMC and the total mana spent to cast a spell, including the Commander Tax, is crucial because many cards in Magic: The Gathering refer specifically to a card’s CMC. These effects can target, destroy, or interact with cards based on their intrinsic mana value, not the modified cost paid to cast them.

Consider the card Terminate, which destroys a creature. You can target your opponent’s commander with Terminate even if they paid the commander tax because Terminate looks at the creature’s printed CMC, not how much mana was actually spent to cast it. Similarly, a card like Counterspell only counters a spell with CMC 2 or less. If your opponent has cast their Commander for the fourth time and you want to Counterspell it, you can’t if the CMC of the commander is above two.

Impact on Card Interactions

Numerous cards interact with spells or permanents based on their CMC. Cards that search your library, such as Chord of Calling, look for creatures with a specific CMC. Spells like Swords to Plowshares can exile creatures, regardless of how much they cost to cast. Understanding that Commander Tax doesn’t change CMC is vital for accurately assessing card interactions and strategic gameplay.

Common Misconceptions

A very common mistake is that the Commander Tax influences abilities that care about CMC. It doesn’t. The Commander Tax only affects the casting cost. It is a cost that is added at the time the commander is being cast, not part of its inherent properties.

Example Scenarios

Let’s examine a few practical examples to solidify the concept:

• Scenario 1: Your Commander, Derevi, Empyrial Tactician, has a CMC of 3. It’s been cast once already. You now need to cast it again. You will pay 3 (the CMC) + 2 (the Commander Tax), totaling 5 mana. The CMC of Derevi remains 3.
• Scenario 2: You cast Feed the Swarm which destroys target enchantment or planeswalker. If your opponent has an enchantment with CMC 3 on the battlefield, Feed the Swarm can target it, regardless of how much your opponent paid to put that enchantment onto the battlefield initially.
• Scenario 3: Your opponent casts their commander with a CMC of 4 for the third time this game (costing them 8 mana). You cast Essence Scatter which counters target creature spell. This spell can target the commander because Essence Scatter only cares about the fact that they are casting a creature spell. The additional cost does not affect the spell’s eligibility as a target.

Frequently Asked Questions (FAQs)

1. Does the Commander Tax increase the mana cost of a Commander in my hand?

No. The Commander Tax only applies when casting your commander from the command zone. It has no bearing on the cost to cast your commander if it’s located elsewhere (e.g., in your hand or graveyard, though it would likely return to the command zone from the graveyard).

2. If I copy my commander, does the copy have the Commander Tax?

No. A copy of your commander is a new permanent. When it is cast, it is considered a new commander and will not have the Commander Tax applied.

3. Does Commander Tax affect cards that search for a specific CMC?

No. Cards that search for creatures or spells with a specific CMC are only concerned with the value printed on the card (or calculated as described above for variable mana costs) and not with the total cost you paid. For example, Collected Company can grab two creatures with CMC 3 or less, regardless of whether a player paid additional mana (like the Commander Tax) to cast a particular creature.

4. Can I use cards that reduce casting costs to offset the Commander Tax?

Yes. Casting cost reduction effects can be applied to reduce the total mana you pay for your commander, including the Commander Tax. For instance, if you have a Herald of War reducing the cost of creature spells by {1} and you’re casting your commander from the command zone for the second time, the Commander Tax would increase the cost by {2}, and the Herald of War would reduce it by {1}, resulting in a net increase of {1}.

5. Does casting my Commander from anywhere other than the command zone still increase the Commander Tax?

No. The Commander Tax only applies to casting your commander from the command zone. If you somehow cast your commander from your hand, graveyard, or exile, it does not incur or increase the tax. However, it will return to the command zone if it would be exiled or put into the graveyard.

6. If my commander is exiled, does it still return to the command zone?

Yes, if your commander would be exiled, you can choose to return it to the command zone instead. This is a replacement effect and you will still have to pay the Commander Tax when casting it.

7. Does the Commander Tax reset if the Commander changes zones (e.g., bounces to my hand and then back to the Command Zone)?

No. The Commander Tax is cumulative throughout the game, regardless of where your commander has been. Each time you cast it from the command zone, the tax increases by {2}.

8. Can I pay the Commander Tax multiple times in one turn to cast my Commander more than once?

No. You can only cast your commander once per turn unless an effect specifically allows you to cast additional spells. If you are able to cast your commander multiple times, you will need to pay the Commander Tax for each instance it is being cast from the command zone.

9. If my commander is countered, does that count as casting it for the Commander Tax?

Yes. If your commander spell is countered after you’ve paid the mana and the Commander Tax, it is considered to have been cast. The next time you cast it from the command zone, you will have to pay the additional {2}.

10. What happens if I cast my Commander for free (using an effect like Omniscience)? Do I still pay the Commander Tax?

Yes, if you are casting your commander from the command zone, you are still obligated to pay the Commander Tax. Even if Omniscience allows you to cast it without paying the mana cost, you must still pay any additional costs, including the Commander Tax.

11. Can I reduce the Commander Tax with cost reduction effects like Training Grounds?

No. Training Grounds only reduces activated abilities of creatures you control. Since the Commander Tax is an additional cost you pay as you cast your commander, it cannot be reduced by Training Grounds.

12. If someone steals my Commander, do they pay the Commander Tax?

Yes. When another player gains control of your commander and casts it from their command zone (if they choose to designate it as their commander), they pay the Commander Tax, and it will be added to the cost of the card each time they cast it. However, if the commander then returns to your control and you cast it, your Commander Tax count will remain where you left it. The commander tax is associated with the player that controls it, and when it comes under your control it is added to your total Commander Tax.

In conclusion, the Commander Tax is a separate and distinct concept from Converted Mana Cost (CMC). Understanding this difference is paramount for navigating the complexities of Magic: The Gathering and making informed decisions during gameplay.
