Well, Excadrill is only 2 feet tall, so it's not much of a threat. :P
Joking.
Playing on PO, I haven't come up against much difficulty in facing an Excadrill. Thundurus, maybe, but I haven't seen many of him. Just a simple EQ, Fire Blast, or something, quickly kills Excadrill. So I don't think it's really necessary, based on my experiences.
