Well the thing about countering a single move is the method in which to do it. Of course, we aren't about to make a move that goes "Prevents the foe from using Trick". We could instead create a move/ability that counters a group of moves. For example, an ability that grants immunity to non-damaging Psychic moves.
Trick may not be used in every match but equally controlling moves are used as well. Any OU team generally has any of the following: Trick, Taunt, Encore, Torment etc
