BABY BOIZ RULES v1.0
1/8/26

1. Overview

Baby Boiz is a custom Magic: The Gathering format derived from Canadian Tiny Leaders, designed for fast-paced, low-curve gameplay with flexible deckbuilding and a focus on expressive, often custom, commanders—known as Baby Boiz.

 

 

2. Deck Construction

• Decks must contain exactly 50 cards, including the Baby Boi(z).

• All cards must have a mana value of 3 or less.

  • ​For Modal Double-Faced Cards (MDFC), this applies only to the mana value of the front face of the card

(​Refer to Magic: The Gathering Comprehensive Rules 202.3 for more information on calculating mana value)

• Decks must follow singleton rules: No more than one copy of any card, except basic lands.

 

 

3. The Baby Boi

• Each deck is led by:

  • One Baby Boi (commander), OR

  • Two Baby Boiz with Partner

• Baby Boiz begin the game in the Boyzone (command zone).

• Baby Boiz determine the deck’s colour identity, following standard MTG rules.

 

 

3.1 Partner Baby Boiz

• Players may use Partner commanders under the following restriction:

The combined mana value of both Baby Boiz must be 4 or less

• Legendary creatures without Partner may be used as if they do have Partner if it has been approved by the playgroup prior to use.

• All other Partner rules function as normal.

 

 

3.2 Custom Baby Boiz

• Custom Baby Boiz are permitted, and encouraged.

• They must be:

  • Approved by the playgroup prior to use

  • Clearly documented (rules text, mana cost, colour identity)

• The playgroup may maintain an Approved Baby Boi List.

 

 

4. Starting the Game

• Each player starts at 20 life.

• Each player draws a starting hand of 7 cards.

• The player who starts the game does not skip their draw step.

 

 

5. Mulligans

• Players may take unlimited free mulligans within 5 minutes of drawing their first hand.

• Each mulligan:

  • Shuffles the hand into the library

  • Draws a new hand of 7 cards

• No card disadvantage is applied

• The player who has taken the fewest mulligans may take the first turn

  • If more than one player tie for the fewest mulligans, those players can decide who takes the first turn by any agreed method

 

 

6. Gameplay Rules

All standard Magic: The Gathering rules apply, except as modified below.

(Refer to Magic: The Gathering Comprehensive Rules)

 

 

7. Casting Your Baby Boi

• Baby Boiz may be cast from the Boyzone.

• Each time a Baby Boi is cast from the Boyzone, it costs {1} more for each previous time it has been cast from the Boyzone this game. (This replaces the standard +{2} command tax.)

 

 

8. The Boyzone

• The command zone is referred to as the Boyzone.

• If a Baby Boi would:

  • Be put into a graveyard

  • Be exiled

  • Be put into a hand or library

• Its owner may choose to return it to the Boyzone instead.

 

 

9. Win/Lose Conditions

• A player wins or loses the game by:

  • Any condition described in Section 104 of Magic: The Gathering Comprehensive Rules (excl. Rule 104.3j) , OR

  • Any alternate win condition printed on a pre-agreed custom Baby Boi card

• Commander damage is not used in this format.

 

 

10. Banned Cards

• There is no general banned list carried over from other formats.

• The only banned cards are:

  • Cards officially banned for real-world harm or offensiveness (see list HERE), AND

  • Cards on the Baby Boiz Banned Card List, AND

  • Cards explicitly banned by the playgroup.

• Players are obliged to reveal all cards in their decks for which the cheapest printing has a current market price of AUD$20 or more (e.g. if a player has a AUD$600 Secret Lair printing of Sol Ring which would otherwise have a market price of AUD$11.50, the player is not obliged to reveal it). The playgroup may agree to ban any or all of the cards revealed this way.

 ​​

 

11. Sideboards

• Sideboards are not permitted.

 

 

12. Spirit of the Format

Baby Boiz is intended to be:

• Fast

• Interactive

• Slightly degenerate

• Socially self-regulating

 

Players are encouraged to:

• Push the boundaries (a bit)

• Design fun custom Baby Boiz

• Avoid turning the format into solitaire

 

 

13. Governance

• All disputes, rulings, and philosophical debates are resolved by The Boi Band. 

• The Boi Band may:

  • Amend the Bay Boiz Format Rules

  • Ban cards

  • Unban cards

  • Regulate custom Baby Boiz

• Bans are based on:

  • Power level

  • Gameplay experience

  • “General vibes” consensus

• The Boi Band may add and remove members at its discretion.

  • The first Boi Band is comprised of the co-creators of the Baby Boiz format. I.e. the "🌈🦄 Mana Dorks💖" group chat.
