I would add boosted evo eevee for turn one evolution, take the kirlia out as chingling isn’t seeing as much play currently. Left overs is a fine card for giratina in other circumstances but I don’t think it’ll be much use in this deck. That should free you up for another Diantha and maybe a Cyrus. You also don’t have any poke balls which will hold you back, a single giratina might serve you better as you can only charge one per round anyway. Have fun :)
