The following is a tenative list or criteria of banned cards in relation to Ebon Dawn sponsored events. If you have any questions regarding any card you may think that should be banned or is borderline legal, you need to discuss it in the "Town Hall" thread in the forums.
_____________________________________________________________________________________
INFINITE MANA: Infinite Mana is banned. If any card or combinaton of cards would cause another player to gain infinite mana on any turn, or the condition exists, then a player is automatically disqualified from the event. It is O.K. to produce insane amounts of mana, but only if it does not meet an "INFINITE" condition.
INFINITE TURNS: Infinite Turns is banned. If any card or combination exists were a player would gain more than 5 turns in any given turn, then he/she is DQ'd.
LAND DESTRUCTION: Land destruction is limited to only non-basic lands. You cannot destroy or bounce basic lands, however you can destroy/bounce any number of non-basic lands. Enchant or Thievery spells are allowed, but if the caster stealing (Basic Only) all of a player(s) lands prevents the owner of the stolen lands from casting any spells, this is considered a "LOCK DOWN" condition and he/she will be DQ'd. This condition (thievery/enchant steals) does not apply to non-basic lands.
INSTANT WINS: Instant Win conditions is banned. If a card or any combination of cards would allow you to win regardless of life total, or a player meets condition X or Y (Battle of Wits, Mortal Kombat, Door to Nothingness, Phage the Untouchable, Etc.), then he/she will be DQ'd.
INDESTRUCTABILITY: Indestructability is allowed, however if a card or combination makes all permanents of a certain type or all cards in general invulnerable, then it is banned.
LOCK DOWN: Any combination of card(s) that could potentially lock-down a game or player is banned from Ebon Dawn events. A "Lock Down" condition exists if a player is prohibited from ever taking a turn (see Infinite Turns condition above), playing a spell, stripped of mana casting capabilities (basic land only), or any combination not described that meets a LOCK DOWN condition.
ANNIHLATOR MECHANIC: Self explanatory. It can be used but once a player decides to sacrifice a basic land then he/she who used the ANNIHLATOR mechanic is DQ'd during "Core" weekly events. This mechanic is not banned in the "After Hours" events, only the "Core" events is it banned if a player decides to sacrifice a basic land due to this mechanic. USE AT YOUR OWN PERIL IN "CORE" EVENTS!!!!
Below is a list of cards banned from all Ebon Dawn events sorted by color.
