That's fine, and I'll check it out. I'd recommend Lessa 1, Lessa 2, Tower of God & Hellper if you want some good ones to read. Lessa is a mythology mixed with D.Gray Man & Black Cat. Tower of God is basically your shonen manwha and Hellper is just BEAUTIFUL.
You need to. It's a very good manwha filled with philosophical lessons and emotion. I recommend it to lots of people who like self reflection or messages in their reads.
So you're basically going along the route of my second fragment but defending it(?). Tarot Mimicry, there are only so many tarot cards you can borrow from. You can say 'nearly every power' but realistically, tarot cards are limited and to copy them is to one's interpretation. To change that...

I think for a starter character, 4-5 should be the maximum. Think of it like a dysfunctional Pokemon if you will. You get 4 basic powers/moves on a creature and as you develop, you can drop old skills for new ones. However, we can remove that latter part in roleplay since... well... it's roleplay.
