I have been testing my team out in battles, and I noticed a few things. First, except for Serperior, my team lacks speed. Second, I lack anything to deal with Fire types, such as Talonflame and Mega Charizard; and other than Heatran, I don't have much to deal with Steel types. Third - and this is the most glaring problem with my team, which I somehow failed to see before - it is entirely specially based, so it will have a very hard time dealing with specially defensive teams, such as Calm Mind Sableye and Espeon, etc. I was thinking of replacing Togekiss, as I like the synergy of the rest of the team. Do you have any recommendations? I was considering Choice Scarf Excadrill or Choice Scarf Garchomp. I would do Choice Scarf Terrakion, as I had originally intended, but my 4 IV, which has a Jolly nature and perfect IVs in HP, Atk, Def, and Spe, has only a 7 in SpD, which is just not going to cut it. Any thoughts?
Air Balloon is a better item to use on Heatran than Rocky Helmet. It lets Heatran dodge Ground attacks even if the item is one time use only.
I don't think Gastro Acid is useful on Serperior. Serperior can already eliminate Azumarill and Diggersby, the premier Huge Power users, with a Leaf Storm. If you can't breed for the right Hidden Power type. (Fire is preferred), use Taunt to better deal with defensive Pokemon
Just use the Terrakion. Defensive IVs don't matter on offensive Pokemon IMO.
