Its still against the spirit of the game.
If you have 5 pharaoh and still need a 6th I dont mind, but if you trade everything is there still a collectible card game?
You aren't really trading, you generate extra copies, which is different.
Especially trading holy cow seems weird as it isn't something you can just get in arena. It is still an unobtainable and you can't get use it in tournaments.
I think putting up a holy cow farm just for trading is kinda lame. There is no reason it should be up for trade.
A lot of people have farmed the cows for many days just to get a single copy ... or none at all. I dont think its fair to trade it for any number of rares you can just get in arena.
Fair point.
My main reason to create this thread was to give people a faster way to obtain one specific type of rare, and coming up with the unobtainable card idea was more of an attempt to try and add appeal to people who already have 6 copies of unupped & upped rares.
I figured that the idea itself would be pretty controversial since, as you mentioned, this method of farming is just inflation with cards instead of money. What I'm unsure of is if it's worth the risk to keep this thread up, let alone post it in the first place.
EDIT: The bit about unobtainable cards is now a footnote, warning about the controversy of both it and the process in general.
