A good arcanine set ;
Arcanine (M) @ Life Orb
Ability: Intimidate
EVs: 252 Atk/252 Spd/4 SAtk
Naughty nature (+Atk, -SDef)
- Extremespeed
- Flare Blitz
- Morning Sun
- Hidden Power [Grass]
Extremespeed, Flare Blitz, and Morning Sun are all staples on Arcanine these days. HP Grass is effective for netting a kill on Rhyperior, however, if you find that you don't need it, change the nature to Adamant and use toxic instead, which allows you to actually do something to Milotic and Slowbro. Though this isn't a bulky set, it is still effective.
For Venusaur, the standard SD is the most effective.
Venusaur (F) @ Life Orb
Ability: Overgrow
EVs: 252 Atk/4 Def/252 Spd
Jolly nature (+Spd, -SAtk)
- Swords Dance
- Power Whip
- Earthquake
- Sleep Powder
Sleep powder is just a good move, allowing you to usually set up a SD. Power Whip is just simply a strong attack, though it does not have perfect accuracy, the damage output makes it better than seed bomb. Earthquake gives you great coverage, especially good for hitting things like Raikou and Registeel.
