Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn, if your "Ursarctic" monster would Tribute a monster(s) to activate its effect, you can banish 1 Level 7 or higher "Ursarctic" monster from your GY instead. Each time a monster(s) is Special Summoned, place 1 counter on this card. Once per turn, if a monster(s) is Special Summoned and an "Ursarctic" Synchro Monster is on the field (except during the Damage Step): You can remove all counters from this card (min. 7), then target 1 monster your opponent controls; take control of it.
