Dear Wizards of the Coast Team,
I am writing to share my feedback regarding the balancing of the Competitive Brawl format. This specifically concerns the following cards in the screensshots.

Strip Mine:
With the card "Strip Mine", the issue is that in Landfall / Land-based decks, it allows players to simply destroy all opponent lands.
Thassa's Oracle & Demonic Consultation:
With "Thassa's Oracle" and "Demonic Consultation" (Pakt des Verderbens), the issue is an infinite combo loop that exiles cards until the library is empty, causing an immediate win/loss on the spot. It feels completely unfair and uninteractive.

These cards are currently so powerful that they severely restrict the metagame. Please also refer to the attached screenshot.
I kindly ask you to consider reviewing and banning these cards.
Thank you for your time!
Best regards
