I barely play the game and made quite a bit more than this in terms of DEC and SPS. I found that the best way to optimize the air drops is to sell off as many cards as I can, and just hold the DEC.

For a while, I was renting out cards and making around 140 DEC/day (the market value of rentals spikes near the end of each season.) I find that it is more profitable to sell off high value cards, and just invest in new cards that are likely to be high value in the future. I've started collecting gold foil chaos cards while they're cheap.

I started playing the game in 2018, but I've only played maybe 2 or 3 seasons each year. I've used credits to buy cards and packs here and there, and I've had a couple of lucky pulls from loot chests.

I have 1128 SPS staked, 42k DEC in the game, and another 10k DEC stuck in my ethereum wallet. The present value of my deck is $900 (by list prices) and my CP is 19k.

The value of my deck a couple of weeks ago was $1700, but prices have generally dropped and I also sold a lot of my cards. I had to cash out much of the DEC in order to make rent this month. For a bit I had over 200k DEC in my account.

It seems to me that Splinterlands rewards investing in the game far more than playing the game.

Art imitating life.
