How about a lottery feature that allows you to ‘draw a ticket’ just once a day and then checks all your stored Pokémon’s OT IDs? Just like in the games but allowing you to actually use all your Gen 3 Pokémon (on Trigger’s PC) to up your chances, not just the ones you happen to have stored on the game whose cartridge you’re playing on at any given moment?
Just a thought I had while collecting my daily prize (usually PP Up) from the one Emerald game I collected OT IDs ending in 00–99 for.
