Main

How 【Main】 works

【Main】 marks an effect you can use during your own Main phase, the part of your turn where you deploy Units, pair Pilots and set up before attacking. Command cards with 【Main】 are the proactive half of your deck: buffs before combat, removal to clear blockers, resource effects.

The timing is the whole restriction. 【Main】 effects can't be used during battles or on the opponent's turn, so a card that needs to matter mid-combat has to be 【Action】 instead. Choosing between the two is most of the skill in building a Command suite.
