Also known as “Limited Infinity.”

This format was originally designed and promoted by Stephen Menendian back in the early 2000s. Read his article from 2004, when the format was brand new:

Article: Limited Infinity

Type 4 is the “infinite mana, infinite decisions” format: the table shares a limitless mana pool, where the real constraint is what you’re allowed to cast each turn. It plays like the most dramatic parts of Commander—big spells, huge swings, politics—without any initial development.

Proxy Friendly house rules:

1. Players share an infinite mana pool that never empties between turns and phases.

2. Players can use the infinite mana pool to pay the cost in the top right corner of a spell once per turn. Alternate costs, additional costs, and activated abilities are unrestricted.

3. Infinite responding abilities are won by the defending ability.

4. Spells and abilities that can directly win the game are banned.

5. Players start games with 5 cards in hand.

6. One mulligan for a new hand of 5 cards.

7. Seat 1 draws a card to start their 1st turn.

8. The maximum hand size is 7 cards.

9. Players start the game with 20 life.

10. Custom cards are mythic rarity.

11. Tournament games are 30 minutes and must have a winner. Read about “Sudden Death” below.

Rule exception:

• If mana from an ability, like Cascading Cataracts, filters the infinite mana pool and pays the entire converted mana cost (top right mana value of a card), that spell doesn’t count towards your one spell per turn limit.

Sudden Death:

• Sudden Death is an emblem that starts each game in play.

  1. No Time — When game times expire, this emblem takes effect after the current turn ends.

  2. No Escape — Each player loses 5 life during each player’s untap step. If this effect would bring a life total to 0 or less, set that life total to 1 instead.

  3. No Mercy — At the beginning of each end step, each player who didn’t take a game action loses 1 life. If this kills each player, this only effects the active player instead.

  4. No Choice — At the beginning of each cleanup step, if a single player has the highest life, that player wins the game.

• You can view the Sudden Death emblem in the Token section of the Custom Set card gallery.

You’ve got two primary options:

1. Draft Mode (recommended): designed as a 4-player free-for-all (just like Commander), where each player drafts 3 packs of 15 random cube cards (following normal limited draft structure) and then plays with a minimum 40-card deck and up to a 5-card sideboard. This is the intended experience with various archetypes to discover and explore.

2. Chaos Stack Mode: Shuffle up a random stack and draw off the top for a wilder, faster “see what happens” game.

Draft Mode Options:

• 4-player draft (1 pod) Recommendation: Choose your favorite 200 cube cards and curate your own meta for your playgroup. This leaves 20 undrafted cards available for effects that add cards to hand from outside the game.

• 8-player draft (2 pods) Recommendation: Choose your favorite 385 cube cards and curate your own meta for your playgroup. This leaves 25 undrafted cards available for effects that add cards to hand from outside the game.

• 16-player draft (4 pods) Recommendation: Choose your favorite 750 cube cards and curate your own meta for your playgroup. This leaves 30 undrafted cards available for effects that add cards to hand from outside the game.

• New custom card expansions are released every few months to evolve the experience.
