I'd be happy to trade you one, but if you're looking for something specifically for Terra I recommend Dewpider. The field makes Special one stat and turns Liquidation into a Special move, so Araquanid becomes quite a monster that can easily plow through her team and carry you to victory. I'll need a bit of time to get either one, so let me know if you want one or both and I'll let you know when I have things ready.
