>>41402624I'm new to EV training myself, but I'm going to try doing the money route since it seems relatively straightforward.
I have a lv100 G-max Meowth with Amulet Coin, and I just need to pull off 3 G-max Goldrushes in a league match (coins don't drop from raids sadly).
Each win nets me ~115k (99,999 from Goldrush, ~16k from match reward), and with vitamins at 10k a pop, I just need to win 5 matches to buy enough drugs to max out EVs.
