I'll analyze the current meta across all formats to make data-driven ban/unban recommendations. Let me gather comprehensive data for each format.
Now let me check some key cards that might be problematic across formats:
Let me get some sources for recent tournaments to validate the data:
Based on current tournament data, here are my data-driven recommendations:
Ban: Guide of Souls
Predicted Impact: Meta would diversify significantly. Tron, Esper Blink, and Domain Zoo (currently 7-8% each) would likely rise to fill the void. Blue Belcher's strong 55.26% winrate suggests it could become more prominent.
Ban: Cauldron of Souls
Predicted Impact: Dimir Midrange and Mono Red Aggro would likely become tier 1. The format would shift from combo-centric to more fair midrange/aggro battles.
Ban: Reanimate
Predicted Impact: Meta would become much more diverse. Mono Red Prison, Show and Tell, and Delver variants would gain significant ground. Format would shift toward more interactive gameplay.
No Changes Recommended
Unban: Fastbond

Sources: Data from 33 Modern tournaments (85% MTGO, 15% Melee), 78 Standard tournaments, and 56 Legacy tournaments from August-September 2025.
