The Archer one is easy just use ibuki or any other lancer with 50% np charge

The avenger one is harder because enemy have more hp and I barely clear it without using face card it's easier with
-np4+ mlb blackgrail
-Np4+ unlocked append 5 so you can use arcueid skill 1 again in the next wave just need append 5 lvl 1
