For competitive ladder,
I take advantage of Electric Seed. When Electric Terrain is active, Electric Seed gives Koko a defense boost, but also doubles Acrobatics' power (55 power w/ item ; 143 power w/o item. It is stronger than Brave Bird's 120 power. STAB Wild Charge (90 power) is stronger than STAB Thunder Punch (75 power), but Thunder Punch doesn't deal recoil damage. Hidden Power Ice is a check for Lando-T and Gliscore. And finally, I have Roost as a Heal move for Wild Charge's recoil. I chose Nature's Madness for the replacement because Nature's Madness can half the health of any mon, including Chancy-Toxic walls (I hate dealing with those).
Tapu Koko @ Electric Seed
Ability: Electric Surge
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Acrobatics
- Thunder Punch / Wild Charge
- Hidden Power [Ice]
- Roost / Nature's Madness
Koko has 394 max speed, so it's faster than most. Koko out speeds Base Greninja (377) but falls to Ash-Greninja(399). Lando-T has 309, so Hidden Power Ice is a pleasing check.
