I had a little over 400 greens at the start of this season but used them to power train. Im now storing them up and want to get around 2000 or so to do mega power training in a few seasons time.

I think thats a better use of packs if possible rather than a few at a time.

Im also trying now to use very little tokens as farming has become harder. Stockpiling the packs will help push the tokens to last longer.
