[190] Pokemon became one of the first Japanese media franchises in which both the localization of the anime and the licensing of merchandise was handled by a single company, as well as a non-Japanese company
The Beta cards are largely without any illustration, while Gamma cards are fully illustrated with clip art (mostly borrowed from Dungeons and Dragons manuals) or hand-drawn illustrations
The cost you paid and the cards mana value are not the same thing, which is good because otherwise half of Magic would need a spreadsheet and a small claims attorney
Other cards I would consider cutting: Skullbriar, the Walking Grave (too slow imo unless he is your commander), Blisterpod (needs to die to get the token), Pawn of Ulamog, Vorapede, Village Rites, Gray Merchant of Asphodel (starts to shine with lots of reanimator stuff), Woe Strider, Scion Summoner, Brood Monitor, Deathreap Ritual, Commander's Sphere It's tough to suggest cards for a budget deck
