>>37940359Gyms and Trainer battles aren’t too different, just no items or abilities. You still have Physical/Special Split.
Breeding is completely removed, and EVs are replaced by AVs, while IVs and Natures are still there.
AVs essentially are EVs, but each stat can have 200 each, and 1 AV increases the Pokemon’s stat by 1.
Also, stealth rocks are in this game, but Rapid Spin and Defog are not, so the meta is a complete dumpster fire.
