[Updated] How to possibly earn in low tier league

Everyone started at low tier that's a fact.
If you don't have huge budget to climb the league but you want to earn something even though, here is my advice to make a bit of earning in a low tier league.

But first why in low tier league?

First in a higher tier you need to have 100,000 - 200,000 power to stay on the league.
that means if you don't own cards you need to rent a bunch of cards that will cost you around 1.5k - 2k DEC daily.

Some bronze and silver tier players that rents around 1.5k to 2k DEC daily and are not able to climb to Gold and Above I'm sure that they are just losing DEC daily or just breaking even.

My suggestion is that if you are still on Bronze or Silver don't over do the renting.
Rent as less as possible to complete your quest and continue up to 25 battles per day.

You will gain around 100 - 250 DEC in Bronze Tier, 150 - 370 DEC in Silver Tier daily from your Winnings only. Your chest rewards is a bonus.

I usually rent max of 5 cards, Gold Foils if it's cheap and essential monster in Bronze.

Renting Gold Foil has perks aside from the additional DEC on rewards, is the level of the monsters.

If I need a leveled up monsters in low tier I tent to rent Gold Foils rather than leveled up Regular Foil because it almost cost the same.

and Gold Foil summoner in Silver Tier. I don't rent summoner that cost 60 DEC and above

Win rate is around 60% so in 25 battles that's 15 battles won.
Multiplied by average 25 DEC per winnings in silver is 375 DEC Daily.
This is average it might go up or go down in actual.

That is how I manage to save up DEC daily.
I save my DEC also because of SPS Airdrop.

Previous: Currently I have 15k DEC and earning about 3 SPS Daily.
My initial investment is the spellbook only and a bunch of quest pots.
Started July of 2021.

Current: 32,360.782 DEC and earning about 5+ SPS Daily from Airdrop and Staking.

I hope this will help you to start.
Thank you.
