I challenged myself to use weak moves on my Pokémon and then EV and IV them, and I got where I should be, past 100-wins! But around 150 wins, I always lose. Is is because I need better "weak moves" NOTE-Don't give me lethal moves like Thunderbolt, I'm challenging myself. Anyone who does that will be warned, then reported second time.
The main main (ish)
Hidden Power Ground
As I can only do weak moves, this guy benefits well. It can OHKO Garchomp with Silver Wind 90% of the time.
Hidden Power Ice
As I suck with weak moves, this is good as I can get.
Thunder Fang/Protect (tried both)
This guy gives me awesome results!
So, no powerhouse moves, stop asking. =D
