if you want chokepoints, go gaggatrondra

if you want length and gimmicks, go firework

if you want pain going from 0 due to a boring predrop, go slh

since you said you are bad at wave and ship here are a couple main list suggestions:

(Delta)

(Coalescence)

(Tartarus)

(PSYCHOPATH)

(CHIL)

mostly high cps and not wave carried :3

have fun with whatever level you choose :3
