Thank you for the insightful article! I've been trying to be more thoughtful on ranking up and renting so this was a welcome read for me. I'm still mostly a newb and enjoy reading on others' insights on how to enjoy the game more. Followed you!
For this end season, I've been renting cards I often use for earth and water splinters (like flesh golem and wood nymph for earth and so on). I don't think I've rented from the top 20 but I've been lucky so far with none of them cancelling (so far) and is looking at Silver 3 rewards this coming end soon.
