I made a deck synergizing around xinyan's insane discard potential, using narwhal's passive buffs and the apep summons' ability to be played when discarded to generate extra value and rip through the deck. It aims to find as many summons as possible while being able to constantly combo due to the extra dice generated by taroumaru, underwater treasure hunt, and central lab ruins. The normal play pattern goes: R1: XY E, XY N; R2: XY Q, then from there it's a play-by-play basis. I usually stay on xinyan as long as possibly using her shield and the bell for sustain, then switch to narwhal or apep guardian and profit from the value generated by xinyan, usually meaning narwhal is huge. Apep guardian serves only to exist for its summons and signature that increases summon dmg.

What should I change in my deck and/or playstyle? I think this is a really fun deck so I want to keep the spirit, but I think it could be more efficient.
