I hate to say it but the juice =/= the squeeze at this time
Lets say you had 50k DEC... you could lock it up and rent cards for a net 11.88 DEC/D Income...
Or... buy these 5 Bellowmancers for 50k DEC:
Rent them out at 8 DEC/Day each and make 40 DEC/Day 🙌
Just one many examples that outperform the Common Plot at this time - that may change later though!
I will test with Rare/Epic later on :)
