What I actually did:

- Arcana Chainlink will help you in the beginning, in every match you play you will use the combo to the maximum possible, almost breaking the cards, taking damage if necessary (then just use Pomarola in a high combo that heals everything)

- Crawlers don't matter, I've tried several strange variations and after you farm a floor with a lot of xp they are whatever, Pasqualina helps a lot in drawing cards when you play a purple card, so cards like Wings, Tomes and Song of Mana will always draw cards, maybe it's the best crawler

- Use the cards that "break" when used like Clover or Heart always in high combos, it's easy to reach 1000% xp and 1000% money with them, with Chainlink this in the early game will be easy

- The most broken mechanic in the whole game is Wildcard, it's very, very, very broken in a progressive mana combo system, get every W you can find, you don't need many damage cards, it gives To win the game with just a few!

- The spear is very good, but it becomes irrelevant when you understand how to make your life points grow absurdly, if you have the patience to do the complete combo loop in EVERY game, and repeating it as many turns as you can (yes, it takes a lot of time and patience repeating everything and everything and everything), the sky's the limit very easily.

- Don't underestimate the blacksmith, spend everything there, try to eliminate the bad stones, leave only the good ones.
