High-grade, vintage, or limited cards often bring in the most profit, especially when sold on major marketplaces
The shared deck they combined after the game is rumored to still be intact
Old Gnawbone is a big dragon that can generate absurd amounts of mana, and this deck is so good at drawing cards that it could enable some truly heinous sequences where you cast multiple huge creatures in a turn, resulting in Eshki eliminating multiple opponents
Its perfect to build around the insect creature type: It gives you a lot of impact as a 3-mana planeswalker, its +1 loyalty ability widens your board and stocks your graveyard, its -2 is a sac outlet and removal ability, and its -5 ability has the potential to be a finishing move
Make custom MTG tokens that match your theme, your board state, and your sanity (clear stats, clear name, no microscope required)
These can be super fun to play around with, especially in decks focused on enchantment synergies
