oh-my-god-amazing. >.< i could almost always get 2 layers of Spikes, sleep, switch, and finish the job later when i come in to heal my slow team mates from whatever ills they'd befallen. it was just insanely awesome.
i tested Oma out last night, and he actually did a pretty good job. my team mate did a great job at keeping entry hazards off the field, but not everyone will be as adept. i'm very encouraged. :)
