Say I have a Shapesharer copy an opponents Verdant Force. The Verdant Force puts a 1/1 green Saproling creature token onto the battlefield at the beginning of each upkeep. The Shapesharer becomes a copy of target creature until your next turn.
So if I copy my opponents Verdant Force on my turn I'm going to assume that I only get one saproling token and not two? ie. I'd get one for his upkeep but not for mine?
