This is my first crack at a 5th gen OU team. My goal with this team is to rely on resistances and wall breakers as well as my defensive core to wear down the opponent's team and set up for the late-game Drill Sweep.

I'm willing to replace Jelly and Thundurus because they haven't been working as well for me in practice as they should be on paper.
Excachompitar is obvi good and I think any team running these 3 guys has a solid base in OU.
Jellythorn is not as good as the hype led me to believe :/
