How are you guys doing today?
Well, I'm going to tell you how I get my first Land in Splinterlands. Hopefully this can be useful for anyone wondering how to buy lands.
It's not really hard, you go to the market, and you can buy a Land Plot Claim for 23.9 usd (as shown on picture below). Here you get a random Land Plot of any rarity. 
Another choice you have is that you can go Land, and there you can check SALE and look on the region you like who is selling the specific land with a specific price. (I like this choice better because is really hard to get other than a common land when you buy a random plot. The starting price for a common land is 10.usd nowadays.
This is my land, I went for the random plot and got a common one, here it is!
After you get the Land Plot go to Manage, now you need a power core or a runi. You can buy a Core for 5000 DEC.
Once you have the Power Core you now start selecting your workers. (each worker has its own productivity depending on type, level and rarity)
Title and Totems also help on productivity.
Then you will have three choices for your team to start working on, as seen below production is very important but look at the land bonuses so don't be fooled just by production.
Okay so team ready now time for work!! Clicked on saved changes and now... you can create your first production building, I chose a Land mine and bought 150 Time Crystals to finish it first.** IMPORTANT** Time Crystals are cheaper on the market that are on the shop!
Okay back to my workers... why I still have no procution??? Let's see... Worker need Grain and Dark Energy to work. The grain you need to buy it with DEC, when creating your team, you will see how much need need per hour to work. and Dark Energy you need to Stake DEC, you can unstake it at any moment, DEC is not lost or consumed!
so hit on + and stake the amount of DEC required, it is worthless to stake more and if you stake less workers will produce less but they still produce.
and that's it! now just pay attention to have enough grain and then I will make the math if it it's worth it since I have to buy grain in order to produce SPS.
So this is how it looks now, the production still extremly low for the investment. It might now be worth it if you asked me unless you have a good land plot 9 (other than common) fully upgraded with titles legendary totems.
IMPORTANT
Once you add a card as worker and take it back it needs a 4-day cooldown if you want to use it for playing. I realize that late so now my whole Water deck is frozen for RANKED lmaooooo
pictures below of my DJinn you can have laugh.
Anyway, it was an experience and hope this guide help you guys!
Any advice or tips is more than welcome PLEASE.
Enjoy!
