Sure. The Groudon I use for Trick Room simply has max HP, max Attack, is Brave and has a 0 Speed IV. now the magic here is Iron Ball and Fling. Without Iron Ball, Wobbuffets were switching in as I swords dance, and under Trick Room, it Encored me. With Iron Ball, Im slower than Wobbuffet, so it cant pull that on me in Trick Room (watch out when TR isnt up though!). After a Swords Dance, Fling will actually OHKO Lugia if I recall, which is normally a pain in the ass for Groudon.
