Instead of yet another attempt to tweak tokenomics and add more expenses to fix the bot problem, what if we just changed wild league to be vastly different from modern? Like with some or all of these changes.

• Ban all SB cards from wild
• Ban all modern cards from wild
• Re-introduce the low card level penalties for wild
• Cards can only be used at one league above their star level (a 1 bcx legendary is unplayable in gold league or higher)

If these changes were made, it would make wild and modern completely different games, since none of the same cards could be played in both leagues.
This would stop bots in their tracks since the glint and SB cards earned from battling in wild would not be usable to continue building their wild deck. They would have to actually buy or rent every single card they want to use in wild.
It would kill off low level card bots that play up into higher leagues than they belong.
It actually adds value to old cards because they would have an exclusive league where they can be used to earn.
