I wouldn't try that, given that most Talonflame are beginning to run Will O' Wisp just to cripple the rock pokemon that get a free switch in against them.
This Guy IS a good check to Talonflame, most people hate to lose their Talonflame so they run away as soon they See Tyrantrum.
Also most Talonflames I've seen go with
- Flare Blitz
- Acrobatics/Brave Bird
- Swords Dance
- U-Turn.
Tyrantrum can easily get in on any Talonflame STAB and set up DD or just plain kill it.
The Set I've run:
Tyrantrum / Life Orb / 252atk/252Spe/4hp
Adamant
Ability: Strong Jaw
- Ice Fang/Earthquake (For T-Tar)
- Fire Fang
- Dragon Dance
- Stone Edge/Rock Slide (Power or accuracy)
Most Talonflames HATE this guy and after a DD he is a good late sweeper, he also can 2HKO Azumarril with Stone Edge and he doesn't fear Aqua Jet.
