The most commonly banned combos in Gundam War history summon a large number (three or more) of untapped strong units in a single turn in early stages (earlier than the time unit that can be normally paid) and strike to the opponent before s/he can make defenses. Whenever such combo appears in many places in tournaments, usually one or a few key cards will be banned/limited afterward, for more serious cases, the ability of the cards/skills will be changed to outlaw the combo decks. The "quick" ability (especially with untap ability) was another type of cards that is the main target of target control, as "quick" originally did not count as a limit of cards that can be paid in a single turn. The "quick lands" were banned in early 2008, and the "quick" rule was amended in August 2008. Cards with quick ability are also counted as card-paying limits; they can no longer played all at once in a single turn. The remaining type of limited card related to destroying lands, which will give a great disadvantage to multi-color decks, especially decks having Celestial Being's unit.
