Well it depends on what you mean by "catch up" - because I mean get up into Champion bracket, win in tournaments, etc. The only way to do that is with a lot of money, or time.
For those who have been in since 2018-2019, they've got the time in now, regardless of how much money they spent, so many have had their accounts go up 200x or more.
For those of us getting in in 2021 (or who sold everything in 2019 - doh!), it's either put in a lot (I dumped almost every crypto I had) or wait a few years while you grind.
Well indeed if we talk about the Champion bracket thats needed a massive investment, even the cards are only rented....
Right now I mostly thinking about the Bronze and Silver leagues and mean the "catch up" accordingly. Step by step, there is always someone ahead to catch up. I guess its some grinding ahead, but still without this voucher thing it would be easier to shorten the backlog.
Ya, bronze is where "anyone" (with time, ability to math, and some gaming skills) can catch up and be somewhat competitive, and push into silver on season-end-day to get more rewards.
But even then, if you jump in and buy $200 worth of cards, you're going to crush people that just did the $10 spellbook and have been grinding for a few months.
