Guys, I'm having a lot of fun playing BDSP's Battle Tower, but there's this one Breloom (with Spore and Substitute) that just destroys my team every single time. I also have problems with a bulky Skarmory.

Any thoughts on how to improve my team? My current team is: Metagross, Gyarados (Dragon Dance), Garchomp (Swords Dance).

I want to reach Rank 10... I keep moving between ranks 2 and 4.
