Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Tyrantrum is super cool. It gets rock head as a DW ability so Head Smash will destroy shit horribly. His defense is so good he can survive bullet punches occasionally. People use him as a strong stealth rock user! Fighting, Ground, Steel, Ice, and Fairy weaknesses blow, but losing Water and Grass weaknesses and resisting Flying, Fire, Electric, Poison, Normal, and Bug is kind of nice.
You are so optimistic about that. Rock Head is certainly interesting.
Talonflame has a cool ability. It does require a lot of support, but a lot of glass cannon pokemon usually do. Since they offer little defensively and the rest of the team needs to compensate. Brave Bird is.. good.
