A while ago (circa 2010-2012) I randomly downloaded an app that was centered around this card game that seemed unique to the app. It reminded me of Magic the Gathering in a sense (except I think it used coins instead of mana or something). It had a surprisingly detailed story that basically amounted to going across this country to fight against three different bosses, and the final boss was fighting the three previous bosses at the same time. I recall that each boss had their own gimmick, with one whose deck revolved around a Sun card (looked kinda like the Sun tarot card), another’s deck revolved around the Moon card (that looked like a crescent moon with a face and maybe dripping blood) that gave each player a copy of the card once it resolved, and I can’t remember the gimmick of the third boss.

I played the game on my Kindle Fire, and I can’t for the life of me remember if it was a free app (if not, then it wouldn’t have cost more than $2). Could someone help me figure out what app this is?
