Combining haste with beefy threats like any of the Ghaltas featured herein or something like Zacama, Zetalpa or Apex Altisaur is a huge play, so its no surprise to see this Dino lord so high up

These scheme cards are the core difference that makes Archenemy work well: the villain player will get additional abilities per turn, with many of these providing an advantage, and room to get ahead of other players
I'd much rather move this choice to when Oink Brawler ETB, making the card relevant in more formats, the choice more informed, and the pig noises more frequent
