Ok, so I've perfected 2 teams now, from help from dem peoples on gamefaqs, so now I'm trying out another team. Only, what should my last poke be? My two special attackers right now are heatran and goodra, and I've got a wall in carbink(underrated). I have NO IDEA what ma last poke should be. Also, are there any other changes I should make? Thanks!
You team could use a fighting pokemon. Keldeo, Conkeldurr and Terrakion (though you already have rock) are all great options.
Also don't use King's Shield and Swords Dance in the same set. That limits Aegislash's attacking options too much. Either throw away KS and include another coverage move like Iron Head or Shadow Claw (and max the speed EVs), or throw away SD for Shadow Ball and make it a mixed attacker (and max SpAtk). The later is my favorite. You can do the mixed set with either max EVs on both attacks or in HP + Spatk.
