IIRC the standard for G/S/C Typhlosion was mixed sweeper...
Typhlosion@Leftovers
- Thunderpunch
- Fire Blast
- Earthquake
- Hidden Power Grass / Hidden power Ice
HP Grass hits Rhydon and Golem whilst HP ice wrecks Dragonite.
You can use DynamicPunch to hit blissey, snorlax and umbreon harder>>EQ, but its not recommended due to shaky accuracy.
Alternately
Typhlosion@Leftovers
- Rest
- Sleep Talk
- Fire Blast
- Thunderpunch / Hidden power [Grass/Ice] / Earthquake
Obligatory rest talk set. Tyhphlosion makes a cool rest talker, but then again everything does in G/S/C lol
Typhlosion@Leftovers
- Curse
- Roar / Rest
- Earthquake / Return
- Fire Blast
Roar stops foe Phazers (Since in G/S/C the faster Phazer attempt to Phaze fails so with a few curses you will by Phazing first) Rest allows him to stick around longer.
This usually wont work, but ive seen it used in lower tier battles. Reason it wont work ? Suicune and bulky waters, Golem, Rhydon etc. Basically the metagame walls you lol. So your better sticking to one of the above sets in higher tier battles and not this one.
