Thanks a lot mawit
Yes you are right, the problem before was that a player could have a deck of 20cards and keep using those cards to get up to Champion level, without ever having to increase their deck.
There was no incentive/reason to grow ones deck.... now with the collection power, a player knows the value of the deck is as important as going up in levels as well. I think this brings a lot of balance to the games economy.
Cheers and goodluck to you too
