Top reason as to why Circle is in Vet is because Abyss had enough late game stuff at the time and Obliterate was probably meant to be a one sided board clear, where as Circle was probably intended as one sided boardclear for the more underdeveloped, at least what I considered underdeveloped before this expansion, Structure Vet Archetype. What I’ed love to see happen is that the factions that didn’t have tile effects get card changes for old cards, like Circle for example, someone suggested that Exhuming Sands be spawned where the spell’s unfortunate victims once stood, making the card stronger and worth playing outside of the 1/100 Hail Mary it’s usually used for. That and to dessicate means to remove moisture from, so turning my own stuff and my opponent’s stuff into piles of dust that will spawn poop on the next turn sounds like a nice investment to me, and it’d fit the name I suppose.
Now this card on the their hand looks like the first of a batch of 9 mana spells which could mean that each faction is getting a nine mana spell, speculation of course. Though if this is anything to go by I feel as though the possible upcoming 9 mana spells are either going to be stupid and pointless or stupidly and powerful and pointlessly game breaking.
But seriously though, it feels like this is the single most boring card this expansion.
