Vet are the oppressors. Idk why everyone complains about Faie (but Dr Astronomy Starhorn and Tyrant Argeon both run light Bender and Emp with much AOE, because I am hateful).
You can play a faie out of cards so easy and get away from all her infiltrate damage and spells (like Spirit). Meanwhile, two obelysks and Vet has board. And 10 cycles once you remove the opening two.
Most walls are not oppressive (gravity well, bonechill) and Faies BBS is annoying chip but rarely wins games from immense value (4 warbirds are 8 damage, but in the long game, not the game of immediate value, it matches value with Argeon, Zirix, Lilithe and Vaath).
Flawless Ghost combo is a real problem. Especially the fabled Gravity Ghost Flawless Spirit. More than luminious skorn, which has yet to outright kill me or deal all 11 damage, or just Ghost who can be sprited for 8.
Flawless with ghost takes no set up which makes cards the most egregious offenders (here in the sense of its a combo you technically shouldn’t be able to do nun one turn). Two gravity wells shouldn’t just get freely flawlessed into ghost Seraphims just because. But with ghost Seraphim existing as he does, flawless can’t be changed.
Flawless as a card concept is fine however. It reminds me of necrotic sphere. I believe I got it from a pack and its transformation ability is incredibly nice and very vanar. The ability to optimize any board into 8/9 instead of taking advantage of the biggest or weakest minion that stuck makes the flawless ghost combo broken, although neither piece is particularly overpowered.
