Reason why i also specifically only talked about tier 7-9 Pokemons.. bms on its own is a great item if you wanna farm tier 6 or lower, since they will appear more frequent.. but for tier 7-9 its Near a waste with the amount of times it fails. So if there were 2 variants. the bms = 25% percentage for 40cc, and for example a different version for 30-35% for about 100-120cc.. theres differene in cost and reward
