Rental ROI in league: Bronze

Hi All,

With the new rewards changes I wanted to explore the return the investment for rentals across various league tiers.
I am starting with Bronze 1 and will go up to Silver 3 , 2 and 1 for the new seasons and will be recording my rental expenses and income from dec earnings and daily reward chests.
Will be leaving the cards earned out for now because I am not looking to sell any of the earned cards.

For now in bronze 1 it's costing me about 120 dec per day to rent a bronze level deck for three splinters. I am not renting a chicken (Too costly) and bear minimum neutral cards.

Let's see how I go! Will report
Hoping to hear about experiences from the community. In case anyone has any data on league income vs rental, it would be great if you leave a comment!
