That's interesting that the cost of renting Rebellion is so much higher, which would reflect the cost of buying too. Quite a few people have said that having Rebellion cards in modern has definitely been the game changer to gaining more wins from just having CL. I have just a few cards that I purchased at bronze level or gained from the few packs I've bought. There's no denying that they helped, but I still only get to silver 3 with them.
I'm looking forward to hearing your verdict. Best of luck!
