Vileplume and other grass types could use Aromatherapy or something to mellow everyone out (pretty sure it makes people high IIRC from the anime), or use Poison Powder or Sleep Powder (what they do is pretty obvious). Parasect could also use Spore (which is 100% accurate btw) to put X-Men to sleep.
Not Archangel, just Angel. It matters because Angel is a giant pussy and Archangel would kick the shit out of him all day.
