It takes too long to make a card in base 1 epic card costs 20,000-40,000 but silver boxes give instantly and are cheaper
It takes days to make 1 legendary card, I'll make 2 mythical by then
Legendary lucky 4 cards are worth 1.200.000 and don't give any legendary, it's ridiculous
Despite all this, the base is also very useful, but the upgrade is very expensive
base = silver boxes
