event advice

i swear i simply must have that saurian event card if it kills me.

ive been going at the event with c6r1 maru hu tao / c3 ferryman furina / c0r1 xilonen / c0r1 yelan. standard rotation, but the natlan tribals on floor 18 were throwing me off a lil. i also have a good venti and kazu, and i think my chiori is decent. tanked on stage 2 floor 19 as furina and yelan were not outputing and personal damage.

are y'all able to floor 20 with hu tao? any tips? if you have do you got a na friend code?
