I am testing this pokemon, and he proved me he's good. He has to compete with rotom-w for the Specs spot, though.
I am using Stunfisk this way:
Stunfisk @ Choice Specs
Static
Modest Nature
252 HP / 4 def / 252 Sp Attack
~Discharge
~Earth Power
~Scald
~Sleep Talk
Although it has subpar attacking stats, Stunfisk has some great assets I want to point out:
1.
It is sexy
2. It is often neglected, and surprises everyone.
3.
It cockblocks Talonflame every damn time. Watch out for Flare Blitz, though.
4. It stands against non-specs Noivern and 2hko it w/ discharge.
5. Stunfisk's typing is both a blessing and a curse. It dislikes surf and earthquake, but it cannot be paralyzed, and it resists stealth rock and stone edge.
6. Static on this pokemon is damn awesome, because of its good HP and average defenses. It can frustrate Mega-Kangaskhans without Earthquake. A more defensive version of this pokemon running leftovers or rocky helmet can work against M-Kanga as well.
7.
109 base HP. (Have I mentioned it before?). At full health, it can survive most nonboosted Earthquakes, Surfs, HydroPumps, even those with stab.
8. Works wonders with Trick Room support.
9. It dents Aegislash, potentially ohkoing him back w/ Earth Power.
10. What's more? It smiles when electrocuting stuff.
11. Able to use Stealth Rock.
