I'd like to suggest a potential change to the Custom Game format. Specifically, I propose bypassing the IV and EV validation when entering battles in this format, so that IVs above 31 and EVs above 252 would remain as they were. The reasoning behind this is to allow for more creativity for those of us working with tools that use unique mechanics. For example, I have a script that generates a format with Pokémon having IVs and EVs outside of the standard bounds, which are valid within the teambuilder but not within any current battle format. This is primarily for unique gameplay experiences that are otherwise impossible in regular formats.
As Custom Game already bypasses many restrictions, it seems reasonable to extend this freedom to IVs and EVs as well. Doing so would enhance its utility for users who want to explore non-traditional sets or simulate extreme battle conditions.
