if you got a good run it is very fun. Returning spellcards is probably the most critical upgrade to have (power overwhelming). Half cost spell for 5 mana and the goldminting one really allowed me to stack the wheels with powerfull stuff and then when I got max hp spell it went up. Somehow it all feels too powerfull and.
thanks a lot for playing the game and your feedbacks. It sounds like a really nice run. I too think Spell-cards return is super strong and it's one of my favorite relic too. I am still adding tons and tons more new stuffs to the game, so come back every now and then, and also share this game to any friends you think that would like this game, it will help me a lot.
