RE: My first gold card ^^

My main account is solidly silver I. At last check I was top 100 on the Silver leaderboard. I wouldn't rent cards just to get to silver I but don't be afraid of it if you can battle in Silver II. The worst that happens if you go to Silver I is that you drop back down to silver II if you have a streak of losses.

Now the jump from Silver I to Gold III is a huge jump. I have done that before and find it much harder to complete my daily quests and get beaten up far more frequently. Don't make that jump until you are ready :)

Happy hunting!
