I've found it takes 12 EV's to properly tell if a stat is even or odd on Lati@s at level 30. So 4 more Defense EV's and 8 more Speed will get your answer. (no depositing required)Latias - #380 (Bold)
HP: 30 - 31
Att: 7 - 9
Def: 30 - 31
SpA: 31
SpD: 27 - 29
Speed: 30 - 31
It's probably not a keep, but how can I even check the stats? I gave it 8 Def EVs and 4 Speed EVs and deposited it in Box. Stats didn't change. Does that mean it's 30-31/x/30/31/27-29/30?
