WARNING: Do Not Read This Story If You Hate Fantasy, Isekai and LitRPG.

But if those three words stir something deep inside of your loins, then read on fellow travelers.

GoC has:

A hot goddess with blue hair and a foul mouth. Check.

Gamer MC with a hard to read fantasy name. Check.

Powering up, acquiring spell cards, trying to cure a disabling STD. Check.

Bad guys with try-hard names and vague agendas. Check.

Mages guild. OP enemies. Shouting the names of spells as you cast them. Running in terror whilst being chased by a troop of chimera baboons. Check, check, check and check.

tldr.

If Pokemon had a baby with Magic the Gathering in a dirty Witcher tavern then you'd have God of Cards.
