Chaos Pack: Best Way To Flip Some Cash

Am really in the mood for some flipping as I was lucky enough to receive some good cards after purchasing some packs. I was able to hold like 13 packs thinking i will keep them till packs become scarce and i can sell them probably at higher price but we all know that is somehow not possible because there is this kind of spirit that will keep whispering to your ears to just open. We all witness the Waka Spiritblade which was sold for 5000 sps and 500 vouchers some days ago and it was sold out within 2-3 mins because i was watching and when i reload the page, it wasnt available, we werent surprised because we all know how good the summoner with poison ability will be when use properly in battle.

Back to the main part, I opened 27 packs which roughly cost 81$ when chaos was selling at $3 on hive-engine and i was lucky enough to get some legendary cards and a gold summoner

A Gold death summoner here (Thaddius Brood) which i sold immediately because am not really in need of it and i need to max the rare thaddius brood which is currently in level 4 after add more to it from the dec i got from the one i sold, also those epic cards too worth some dec

Got this Uriel the Purifier which is a legendary card, already have level 3 of it and still dont know if i should just level it up or still keep it instead since i might need to max it later in future
