The Discrete Philosophy Update

Date: September 24, 2025

Result

A card is said to have multiple sets of characteristics, if it has more than one, of each of the following:

  • Name
  • Mana Cost
  • Type Line
  • Rules Text

In TL:R, every set of characteristics on a card must have a mana value <= 3. If a card has multiple sets of characteristics that may be chosen for casting, each set must independently meet this limit.

The Logic

From a design perspective, cards with more than one set of characteristics are multiple cards sharing one piece of cardboard. Every card must have a mana value <= 3 as determined by each distinct set of characteristics.

Frequently Asked Questions

Q: How do I know if a meld card is legal?

A: We only look at the front face. The back is ignored when considering Mana Value, Color Identity, or other restrictions.

Q: How does Partner/Background work?

A: As long as both cards meet deckbuilding restrictions, you can use them. If you play with more than one commander, you start the game with a forced mulligan.

Q: Can I change my Commander between games/matches?

A: No. Your configuration is locked at the start of the event. You can swap cards between your 49 and sideboard, but the Commander(s) never change.

Q: Can I use cards with X in the casting cost?

A: Yes. We look at the mana value with X=0. If the card has MV 3 or less with X=0, it is legal.

Q: Can I use Adventure cards?

A: Discrete Philosophy Check: Every part of the card must be MV 3 or less. You must check the creature AND the Adventure spell. If either part is MV 4+, the entire card is illegal.

Q: How do I determine Mana Value of double-faced cards?

A: Discrete Philosophy Check: For Modal Double-Faced Cards, both sides must, independent of the other, meet the MV 3 restriction and the color identity of your Commander(s).

Q: How many colors can I play?

A: There is no limit aside from your Commander's identity. If you find a legal 5-color Commander, you can play 5 colors.

Q: Can I use a Companion?

A: Yes. Your companion and your deck/commander(s) must all meet the Companion's restrictions and the TSMCR

Q: Can I use Split Cards (such as Fire//Ice)?

A: Discrete Philosophy Check: Split cards are evaluated by checking each half independently. All halves must have a mana value of 3 or less for the card to be legal.

Q: How do I determine Color Identity?

A: Identity includes all colors in the Mana Cost, Rules Text, and Color Indicators. For double-faced cards, always check the back side (except for Meld cards).

Q: How do I know if I can use a flip card (such as Erayo, Soratami Ascendant)?

A: We only look at the "default" (unflipped) characteristics. The flipped state is ignored for legality.

Q: Does having multiple Commanders affect my mulligans or starting hand?

A: Yes. If you have more than one, you take a forced mulligan at the start of the game.

Q: Can I use digital only cards or cards updated through Alchemy?

A: No. TLR is a paper format. All cards use their Oracle text found on Gatherer.

Q: How does the forced mulligan for more than one commander work?

A: Draw an opening seven, then put one on the bottom of your library. This counts as your first mulligan.

Q: Can I use Serum Powder on the forced mulligan?

A: No. Since the first mulligan is forced and involves no choice, Serum Powder cannot replace it. It can apply to future mulligans.

Q: How does Urza's Bauble work?

A: Looking at a card is a one-sided reveal. Your hand remains your hand. In a physical game, looking at a card with an opponent is essentially looking at it together.
