>>22843661My first ever multiplayer battle was against Shuckle back in Gen 4. It walled my entire team.
To be fair, I was using a full Eeveelution team with no EVs and no idea what natures even did.
Since then, the only interesting thing I've seen is a Struggle Bug+Encore+Helping Hand one in VGC. It was cool but I'm sure other things do it better.
