Pokémon Tabletop

Personally I think carry weight only meaningfully contributes to the game if the players need to strictly keep track of supplies including gear, ammo, food and healing items for survival, but though this system gives you a reference of how much pokémon can lift, it doesn't tell you passive carrying capacities or even the weight of different items, or even how much they need to eat and how finding food should be handled, so it may not be the best system for that. You would have a lot of work to add that in.

On the flipside if you like realism, you might appreciate that they add a pain mechanic to emphasize how the pokémon are weakened as they get worn out by battle.

I don't understand what you mean by trained templates though. They give you some guides on how to easily create enemy encounters but I'm not sure if that's what you want.
