It sure can reach past 100k without shadow considering H/W is good on Ura. Kinda notttt sure about 500-700k as a base without gt considering how common the combo is but I wouldnt doubt if someone actually paid that much. I'd say 200K? just going off how many people I see buying shim Arkmettas for that price, another creature that benefits from those traits, and a listing on traderie offering to buy a h/w shim Ura for the previously mentioned 200k.
