I don't get it, you're confusing lol
It returns all your opponent's abilities. For each ability returned, a gate is returned as well (as in, your opponent loses two abilities from their used pile, they also lose two gates from their used pile). Clear things up, Yoshi?
No... How is that helpful?
The goal is to get three gates in your used pile. They lose however many abilities were in their used pile. That's REALLY helpful.
