I’m wondering what moves a delta-charizard might get in the future. It has 3 obvious choices with dragon pulse, shadow ball, and lunar cannon. But it’s current move pool is lacking for a 4th choice. STAB shadow sneak? Frost breath in place of HP Ice?
Special is clearly the way to go. But with mild it gets a small benefit of no detriment to a STAB priority move. But Timid means it doesn’t lose it’s lackluster bulk.
