Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
It keeps the priority at 0, not -7. It's just as if the pokemon's speed is put to 0 when it's holding it. So a Shadow Ball with Lagging Tail would come out before Roar or any other -Priority move.
I think it should be mentioned that if Choice Banded Tyranitar predicts correctly and it uses Pursuit when the foe switches out, it won't be locked into it. (Sorry if it was already mentioned somewhere.)
The last 9 rated battles I was in, they disconnected at the end. In Free Mode, about 20% disconnect. So Free Mode is much better even though I like the idea of Rating Mode better.
Sometimes you use the Japanese names for Pokemon/Move names and sometimes you use the English names, it's probably best to pick one. But good strategies anyway!
I'm wondering about Alakazam. It's basically a Gengar with better stats, but a worse movepool. It's DW ability can be great with Life Orb too. Why is Alakazam down a tier? I thought it improved, even if there are some great new Pokemon this Gen' to replace, counter it etc.
When me and my brother were playing, he got three crit's in a row! >_>
My brother gave me Silver and it was glitched or hacked or something so I could do some events again! (Like fight your rival in Victory Road or catching the Three Beasts again.)
