Having all cards doesn’t mean that you get the highest rank. You also need the skill of composing a smooth deck which runs stable against all heroes. I payed 20€ and have almost all cards but just because I was playing from the very beginning. I can imagine that especially for new players it’s hard to catch up. So I would say you need to spend money in order to reach ultimate if you start over new. But not hundreds of dollars. I d like to share a pretty strong plant deck where I am convinced you can reach ultimate with just 3 legendaries.
