Many new players to splinterlands don’t realize that certain splinterlands card editions allow you to earn an extra 10% DEC per battle. The Alpha and Promo editions cards provide an additional +10% extra DEC for every card you play. And yes, they stack. So if you play 7 Alpha/Promo edition cards, you will land up getting +70% extra DEC for the battle.

Another way to earn extra DEC is by playing Gold Foil versions of cards which also give you +10% extra DEC. Therefore if you play Gold Foil Alpha or Gold Foil Promo edition cards, these do stack to provide you with an +20% extra DEC. Therefore, in theory, if you play 7 Gold Foil Alpha or Promo edition cards, you will land up getting +140% additional DEC for the battle.

Well, unless you have been an early adopter of splinterlands or haven’t been keeping up to date with the economics of the game -> these editions are costly, especially those Alphas. However, with the release of the rental market, being able to rent these expensive Gold Foil cards are all of a sudden a lot more feasible. You’ve read this far and still wondering how you will earn that extra DEC. Well, read on.

Using the latest rental values from peakmonster.com, the table now paints a different picture. The Mermaid Healer cheapest Gold Foil card will cost 56 DEC per day to rent. Doing back of the paper napkin maths, if every battle you win nets you 40 DEC, adding Gold Foil Mermaid Healer will net you an extra 8 DEC. However, you need to play 7 matches daily to break even on the Gold Foil rental price.

Enchanted Defender and Goblin Chef are two low-cost options that would only take 1-2 battles to pay off the rental costs with the additional DEC they offer per battle.
