This cube consists of the 540 cards with the highest GIH WR from sets that were legal on MTGA in 2024 (LCI-KTK-MKM-OTJ-MH3-BLB-DSK-FDN-PIO).
I took out the top 37 cards by win-rate (e.g. Aurelia's Vindicator, Bonehoard Dracosaur) and replaced them with lands. This gives a complete set of the man lands (restless cycle from LCI and the enemy color lands from PIO), a complete set of the gain lands from KTK/FDN, and a complete set of the ping deserts from OTJ, and a complete set of the Guildgates from PIO.
