Do you feel Marmalmaid is working good in here? I remember using it @1 as well, but I either never drew it or it came already oo late\no targets etc. I would also consider running 1 Butlerusk, esspecially when you have Double Summon.
Oh and, how does Polooza run? I always found it situational and kinda slow, but I never ran more than 1 copy of it. I would suggest running 1 more MST because it's really helpfull here, but that's less urgent I guess.
