Summoned Y!Tiki, but...

So, I managed to pull Y!Tiki for last slot of my dragon team (Myrrh, Nowi, L!Robin), but ffs I got +spd -atk IV which is pretty far from what I have planned for her (+atk -hp/-spd, dark breath+(res), DC+QR build, enemy phase). Well, Im not using lightning breath for aesthetic reason lol.

Should I pull more or stick with my old A!Tiki? Or is there any datamine about her mist breath effect (other than dragon slayer effect) that made her still viable to be built?
