1. I don't think so

1a. No

2. The only one you may want to keep on hand is Idler (to make Super Soldiers which are effective with just 1 soldier) and single-target skill unleashers (Romance, Furinkazan, Seagull).

3. You need to get stronger for Witch Gates, unfortunately

4. There's an Easy Mode for EH, and I am pretty sure it's far easier than Witch Gates.

5. When I'm low on Slimes, I level up HN cards. 2 HN > 1 Slime and 3 max lvl HN is about 2 lv 27 Slime... for a SR card, you can feed 3 max level HN with a Blessing arcana.
