Theyre normally the first Pokemon revealed when a new game releases, and in the TCG, their cards are often extremely powerful (the current reign of Charizard ex attests to that) or immensely sought after due to both scarcity and nostalgia
You can always sacrifice Grinding Station to itself if need be and there are a number of cards that could be used depending on colours and number of artifacts you can bring into play and sacrifice
Ghost Rares have a monochrome, grey coloured look, with shiny silver on the card name and a split image for the artwork of the monster on the card, giving it a pseudo 3D effect
Besides the evolutions, the archetype has the potential to incorporate other Synchro monsters into its Extra Deck pool for greater versatility
They tend to have just enough complexity and a lot of power that exactly fits the bill for what you want in an eternal format
