I've thought about the final quest. To me, the final quest seems almost literally impossible to beat. Look at it this way: All decks have counters. The player posing as God can see your deck beforehand, and s/he should be good enough of a player to construct a counter deck to all decks. Therefore, whatever deck you make, God will always have a deck with a very high chance of beating yours. Unless you have really good draw and God has really bad draw, it's almost impossible to beat God if s/he knows your deck before the fight. And if you can only attempt this quest once, then it just becomes a ridiculous test of luck.
