all depend about demand for current moment, but cards rents better, when season is near to end :D
Of course cheap cards not generate really good profits, but I set up rent for 27% apr and some of them was rented.
Max level cards rent better than incomplete level cards and these cards have 5% bonus collection power!
I think this card is good and totally worth to play with ;) I know that many people play water only with full sneak, but you can play with ranged cards as well.
