Most of the DEC goes back to splinterlands to build guilds, and via tournaments(which palyers will be able to earn DEC even new players). The point of the tool is to manage demand and circulation. New players who do not want to build a nice level 2 or 3 deck for $40.00 can rent cards for .001 a day. but if new players are not Joining constantly increasing, there is nothing in place to prevent cards from becoming worthless or .001 cents. Dropping card value so small just to get new players and ignoring all the time and money current players put in seems bad, this will balance the two.
