Finally got all mah power items. Little by little I ended up with a set that wins the normal Single Subway every time effortlessly, as in no thinking on my part. I'll use it to get other stuff like the Focus Sash too, for the Super Single team. The final version (that's my ingame team so no random IVs/Natures/Evs), as well as how it started in brackets:
Lead: Emboar @ Fire Gem (Brightpowder)
Flare Blitz
Stone Edge (Will-o-Wisp)
Brick Break
Earthquake
Haxorus @ Dragon Gem (Dragon Claw)
Outrage
Earthquake
Dragon Dance (I never use this)
Swords Dance (X-Scissor)
Krookodile @ Earth Gem (Expert Belt)
Earthquake
Crunch
Stone Edge
Outrage (I never use this)
I started tweaking them after every set to make it more reliable and faster, and before I knew it, I ended up with 3 gems and the strongest attacking moves
it was so simple all along! Just be as strong as possible and it'll work itself out!
But yeah I can get the 16 points in almost as many minutes with no trained Pokemon (I think two of them even have negative natures), so I'm happy!
Meanwhile, could anyone gimme Pokerus please (sometime in the weekend)? Once I got that I could start with the shiny Boldore training.
