Hi everybody, I'm new to the forum, hope I can find some answers here.
My friend and I are doing a red/blue vs run where we battle after every gym, and he used the teleport glitch and now has a Mew on his team. I totally forgot about the glitch and now I can't do it until the next opportunity with fly, so I can't just match him.
We all know how broken this thing is in gen 1, so I need to know what the best strategy for it would be? The only super effective moves are bug and they're both terrible, and it's stats are untouchable.
If anybody can name a good counter Pokémon or strategy that will give me a chance I'd appreciate it.
