...Reminds me of this.Good move. I still have a trick up my sleeve. Use Ice beam to form a wall of ice in front of you for defense and also refract your Flash Cannon through it so that a dazelling array or almost unavoidable rays bombards Zwampy!!!
Two can play it that game. Zwampy, use your Hydro Pump to make an aqua sheild, then add Rock Slide to add better defense (yus, I do da Ash method from the anime)
Rock Slide and crush him!
