I think it's more economical to rent these cards, especially the L1 GF legendary cards.
E.g., L1 GF Djinn Biljka is ~$27, the average rental price is 6.5 DEC, for this money, you can rent this card for more than 14 (!) years:

Let's assume $0.8/1000 DEC
Card cost: $27/$0.8*1000 = 33750 DEC
For this amount, you can rent 33750/6.5 = ~5192 days (more than 14 years)
And you are safe from card price inflation as well 😉
When I had a land, I rented 5x L1 GF CL cards, and sometimes the overall cost was ~10 DEC/day (for 12500 PP).
And also, you can find max-level epic cards for only 1 DEC/day
This is a great strategy too, especially to get started!
My plan (and guide) are for those assets I prefer to own and I have been growing my collection steadily by doing this 😁
However, perhaps I should also share a piece on the "Super low budget Land Startup"...
Thank you for adding the Rental Strategy comment!
Ty! From the saved money, additional lands can be bought 😉
I got an idea from this article. I will show the Cost/Production Point on my site for each card. I'm curious as well.
Tag me in it - I'd love to see it :)
