Yeah, I want to play around with Cress in Gardylade too. Plus, while it is sitting on the Bench, you're healing your Gallade AND doing 10 extra damage. Sonic Blade, sure, they can put it on their Bench, but Cress is also putting Damage Counters and improving Gallade's life. Also, it helps with Gardy's Bring Down. AND, if your Gallade needs some healing, normal Cresselia's second attack heals him to full HP. Now, you can say Magmortar all you like, but once he KOs Cress, Gallade gets one extra attack - which is all he needs. Plus, as there is only one Mag Lv.X, TSD gets back Cress. Normal Magmortar may spread, but it'll still need 5 turns to KO Cress, all the while Gallade is KOing him. Now, how can you say it's only "okay?"
