How does the Comic Card Crafting system work, and is it a viable method for obtaining good cards?

The Comic Card Crafting system allows players to combine existing 6-star comic cards with other materials (like Dimension Tokens and Gold) to create 'Crafted' cards. This process adds additional stats (represented by blue stars) to the card and allows for re-rolling of variable options to achieve desired stat combinations like Pierce. It is a highly viable and essential late-game method for optimizing your card set, particularly for achieving maximum potential and specific stat boosts like Pierce damage.
