Again, I'll have to agree to disagree. If you are given a deck and asked to "stack" the cards, you deal yourself the best possible hand with the deck given. If you want to blatantly cheat, you replace all the cards with Aces, which would be replacing all lower level cards with trump cards. Some gyms don't have 20 Sr. aged level two kids to begin with so, those teams may consist of two-level 1 athletes, eight-level 2 athletes, five- level 3 athletes, four- level 4 kids, and two-level 5 kids. They are working with what they have to meet ratio's to max out and that is a "stacked" team. So, 20 Sr. aged heavily skilled level two kids can be considered a "stacked" team in comparison to other gyms. Twenty level 5 kids on a level two would not be considered stacked because they can be "level 5" and that's considered sandbagging.
