@Puri1: Correct me if I'm wrong, but your post specifically implies that Ghostmare, and more generally, Generic Novabows firestalls and SoSa Poison Stalls, don't have a lack of originality and thought, since they don't get an automatic thumbs down like Aetherstall.
Yeah, I was actually thinking about it later and decided I need to clarify my position. If they build any of those you mentioned, I wouldn't thumb it down
iff they used the Oracle card as an essential part of the strategy. So if their Oracle card was a Nightmare/GotP, I would give a thumbs up assuming they won due to it being a well made deck (and not sheer luck). There's unfortunately not a huge selection of decks that can utilize those cards in the excessive amount of 5 apart from Ghostmare, and I don't feel it's fair to penalize the player for getting lucky with the Oracle and using a generic build if it's one of the few that can handle 5 copies of those cards.
This reasoning applies to Fire Shield as the Oracle Card (Novabows firestalls) and Poison/Arsenic as the Oracle Card (SoSa Poisonstalls). What other deck can you make with 5 Fire Shields and hope to be semi-successful? Thus, if I recognize the deck archetype while playing I use this logic to see if the Oracle card was needed and is being used in that build. Now, the "essential to the strategy" bit is important. If they make a Ghostmare because they have Time Tower as their Oracle card,
then I would thumb it down since they could easily have done something more creative. Finally, the reason I single out Aetherstall is because out of the dozens that I have played in Arena, about 80% just mindlessly change the mark (or not) to incorporate their Oracle Card but leave the rest of the deck in the regular old setup. That's boring and cheap, so I just thumb them all down.
I hope that helps explain my apparent thumbs up/down madness
