accidentally wiping out your board with poorly planned -1/-1 counters is never a path to success
This is a very simple card, just a vanilla 4/5 for 6 mana
However, stealing lands doesn't work in every playgroup (although I'd prefer a land stolen with this so I can get it back rather than a Wasteland hitting it), so even though the decks registered is fewer than 500, this hits my Honorable Mention since it can be a feel bad moment to have your Hall of Heliod's Generosity that you are abusing stolen
I was thinking of cards that are impactful enough that can be cast off Jaya's first ability
Its not a bad card, but like all cards, it has things that it is good at and things that it is not good at, and, as a deck-builder, you should be trying to have your cards accomplish things that they are good at
