Trigger Effect
Revision as of 17:37, 9 February 2006 by 84.69.31.14 (talk)
Trigger Monster Effects activate whenever a certain condition on the field, the nature of play, or the progress of the turn, is met.
For example, Mirage Dragon's effect lies dormant, until the Battle Phase. While in the Battle Phase, this monster's effect prevents the opponent from activating any Trap Cards.
