This team-builder/tier thing is so confusing. I just wanted to make a few regular teams. Two ended up being OU, as I assumed they would be. But one ended up being Inverted Balanced Hackmons. How does that even happen??? The "Show illegal" box was absolutely NOT checked and as far as I can tell there's nothing wrong with their moves/stats/items/abilities etc. This is the team: Spoiler: Spoiler All are level 100, female and non-shiny. Venusaur & Venusaurite Chlorophyll, Modest EVs: HP & Sp.A 252, Def 6 Sunny Day, Hidden Power (Ice), Giga Drain, Sludge Bomb IVs: 30,30,31,31,30,30 Raichu & Assault Vest Lightning Rod, Jolly EVs: Atk & Spd 252, HP 6 Volt Tackle, Fake Out, Quick Attack, Nuzzle Haxorus & Dragon Gem Mold Breaker, Adamant EVs: Atk & Spd 252, HP 6 Dragon Dance, Earthquake, Dual Chop, Rock Slide Ambipom & Normal Gem Technician, Adamant EVs: Atk & Spd 252, HP 6 Fake Out, Power-Up Punch, Fire Punch, Double Hit Breloom & Focus Sash Technician, Adamant EVs: Atk & Spd 252, Def 6 Spore, Mach Punch, Rock Tomb, Bullet Seed Probopass & Weakness Policy Sturdy, Modest EVs: HP & Sp.A 252, Def 6 Power Gem, Discharge, Flash Cannon, Thunder Wave How do I fix this??
The Dragon Gem on Haxorus is an unreleased item in Gen 6, you can't use that in OU. Remove it and try again.
Okay well thank you, that was it. I guess the only mystery now is why it was placed it that particular tier...
