Yeah Treecko kinda sucks! My only other pokemon that is half decent is the one that looks like a Swallow (I've been renaming all the ones I use so I've no idea a lot of them are called). I guess il just get used to the new Pokemon & find which ones work for me. That or every time I see a 1st gen Pokemon catch them instead A few of my favorites such as Golem & Raichu are in it. Sadly no Nidoking, they're awesome
