I might be wrong, but they describe it as a pyramid scheme... you will soon be able to reach high leagues only if you paid enough, it's not the talent of the player it's how much he spent...

It's not a game thus, it's a weird investment pyramid scheme when the ones at the top shares the most rewards even if they can't play without a maxed deck.

Also, some explained clearly that instead of buying TONS of cards, they chose wisely which card to boost to be able to win, so they spent, but not enough, thus they will be blocked too, point proven, it's not talent just money power...
