You also get the chance to obtain a full-foil Grusha card if you win the Gym Battle or in the rock-paper-scissor tournament

I wanted to understand how the platform worked, what successful sellers were doing, and how they engaged their audiences
If you stick solely to Vampire Aristocrats like the precon promotes then I think Clavileno and Carmen are about the same power level where it boils down your own preferences and your own meta: Clavileno is cheaper and provides a slow but consistent payoff, whereas Carmen is more expensive but also more explosive and randomly becomes more powerful if you happen to play against decks that sacrifice a lot (fetchlands, treasures, other Aristocrats etc.)
Thats a pain to deal with on its own, but the card also gives other Artifact Creatures you control Flying, Trample, Indestructible and Haste
This was the only way people could get a Mana Crypt until 2016, when it was reprinted in Eternal Masters
