Due to recent update about current rank season rewards, renting has been harder for small players who can't afford much cards.
So we'll talk about some points on how to reduce your expenses on rentals due to increasing prices as season is nearing to its end.
Rent Early
Now this option is what I personally use, I rent gold cards early (3-4 days before season end) so that I wouldn't be caught in the rentals increasing prices which starts about 3 days before season end.
Sniping Cards w/ high bcx
Gold cards aren't the only one benefical for power, take into example a max level rare card which is about 7k power it only costs sometimes about 9 dec which is very cheap unlike gold epic cards which prices starts at 20 dec which sits at 10k power.
Sniping Gold Cards
Now this one is a bit hard considering many players use this option. The way you do it with this is you keep on refreshing till a new card at cheap rental price appears. It can be challenge and even me has a hard time winning a card. Ofcourse, having a fast internet is a good advantage and patience is also a key.
A Heads Up
My general advice is for small players like me , we can invest little by little as this update is a factor for keeping the game alive, also this is to avoid abusing the game as such. Thanks for reading up until here. May we all be blessed with good luck!
