Each season I try to rent to silver 1 with a positive net return on my DEC spent to get there. This season being my example I started with almost 25k collection power. I rented a gold foil legendary card that was worth 50k collection power. Naturally this is slightly expensive but with at least a 50% win rate you can come out with a net positive.
The first part to my strategy is to remain at silver 3 until I have the rank to reach Silver 1 (1600 Rating). Once I have reached it, I rent a 50k collection power card for at least 500CP/DEC. This season I was able to rent the card for 629CP/DEC. The point is there are great deals out there you just need to take a small amount of time to find it. Plus it is definitley worth renting a card for 5-10 days before end of season where the prices will be so much better.
Getting to some math... The card I rented is 79DEC/Day and I rented it for 10 days. So I spent 790 DEC on renting this card through the remainder of the season (Assuming it doesn't get cancelled pre end of season which happens). Now at Silver 1 I avereage around 8 DEC/Win from 100%-75% capture rate sometimes more depending on win streaks or the other bonuses available to me. So If I play eaxh day between 100% and 75% capture rate for the span of me being at silver 1 for the rest of the season assuming my winrate is at 50% here would be the outcome. Say I am able to fit 22 games in until I hit 75% capture rate for 10 days until end of season. That is 220 games total and say I can only manage to win 50% if those games at 8 DEC/WIN. I would earn 880 DEC for those wins and that is a 90 DEC Profit from what I spent to get to Silver 1.
Now with some seperate win rates with the numbers I am using this season.
55% 968 DEC
60% 1,056 DEC
65% 1,144 DEC
So, as you can see you can more than make up for renting a 50k collection power card for end of season especially if you do better than a 50% win rate. Also these numbers can very well be higher if you tack on win streaks plus other bonuses. This is just assuming I am only getting base reward for a win, so it is likely that you would be able to make more than these numbers show.
I really hope this helps someone. I see alot about how hard it is to rent cards and how expensive it can be. It for sure can be expensive if you do not have the proper strategy. This has worked for me for a little while now and I am always able to make up the DEC I spend. Even if I buy the card mid season until the end of the season if I follow this strategy I still come out on top plus some extra reward chests.
