I actually expect this deck list to go down in price a few weeks after BRO releases and then probably start going up as Magic decks often do: Further Upgrades Here are some cards I'd add on a higher budget / you have in your collection: Dauthi Voidwalker is absurdly good graveyard hate stapled to an evasive body Snuff Out and Deadly Rollick are mana-free removal Lightning Greaves is simply better Swiftfoot Boots in this deck since we don't really target our own creatures K'rrik, Son of Yawgmoth, Culling the Weak, and Jeweled Lotus are amazing ramp Vampiric Tutor and Demonic Tutor are the most efficient and flexible tutors, perfect to get whatever we need Currency Converter is essentially a 1-drop mana rock in the deck considering how quickly we start discarding down to hand size
Its three currencies (Coins for cosmetics, Credits for crafting, and Crystals for extra rewards and perks) are all earned by playing the game and claiming them from daily missions, the Battle Pass, and the like
The other half of the pricing issue is likely supply
Budget Pikachus Under $30 (For Starter Collectors) Not every collector is ready to drop $200+ on a single Pikachu
While the general resale price of this card does appear to be declining at the time of writing, its retailing for around $125-150 depending on quality and grading, with some premium quality cards being sold for well over $200
