Yeah, it's more profitable in that way, unfortunately. But the balance declined really fast in recent packs (Look how insane the status and effect is: https://web.archive.org/web/20220929050342/https://shadowverse.gamewith.jp/article/show/347272 ).

In the past at least they restored some overall balance in new sets, like SFL is generally balanced compared to ToG (mainly Lightning Blast's Enhance 10 and Zell when it was 222) and the infamous WLD which made many players left. And even that there is still chance to win without using mainstream decks (unless when I faced the classic op card Dimension Shift). Now it's never.
