The ability to vote using Dec was a godsend by the team at Splinterlands at least for me. Dec is very cheap on Steem Engine, so basically you always turn a profit on each vote if the price doesn't go down as much.

Also, since you have a lot of Steem Power delegate some of that to Steemmonsters and you will receive a daily contribution of Dec.

I delegated 50 Sp from my 83 SP and I am getting 10-11 Dec daily. Just bought more Steem today that will go into delegating to Steemmonsters.

Congrats on your gold deck btw.
