- The Chaos Phase is before your Untap step.
- Phasing is considered an "at the beginning of your turn" effect.
- No spells or effects may be played during the Chaos Phase unless otherwise instructed.
- All triggered effects still resolve during the Chaos Phase, but
neither player may respond to them.
- At the end of your Chaos Phase, roll a Chaos Roll. This roll must always
be resolved as well as possible.
- You MUST take the roll. No matter what, the chaos roll must
be attempted. If there are no targets, then it will simply be
countered upon resolution (fizzle).
- All rolls are considered to be controlled by the person who made the roll.
- All costs for rolls must be paid, regardless of the number targets available.
- If a roll lacks legal targets, fulfill all abilities of the roll that
are possible. (Example: If Fumarole is rolled and there are no creatures
in play, you must still pay three life and destroy a land.)
- All chaos rolls are colorless in nature. (Example: A Dark Banishing
roll can target a White Knight.)
- All cards that are untargetable by spells or effects can not be targeted
by chaos rolls that require a target.
- If a roll forces you to resolve multiple rolls, ignore that roll unless
you are currently on your last roll. (Example: If you roll "Roll 3 times"
and on the second of these three you roll "Roll 3 times" again, ignore
that roll and re-roll your second roll.)
- At the beginning of the game, after turn order has been decided and all
players are satisfied with their opening hands, the first player rolls
- EnchantWorldLands are considered Enchantments and can be affected by
all things that affect Enchantments, but will not affect or be
affected by an Enchant World card coming into play.
- EnchantWorldLands are not considered to be lands.
- When a CounterRoll or RollFork is used, it resolves as though it were
a roll, and can therefore be affected as though it were a roll.
- When a player drops below 1 life, they are healed to 0 life and must
perform a Spite Roll.
- A Spite Roll is a Chaos Roll, and if the roll allows the player to
gain life, they are able to remain in the game.
- No spells or effects may be used between the healing to 0 life and the Spite Roll.
- Only a Roll that gains you life will have any effect. Ignore any non-lifegaining Roll.
