The ban list idea sounds interesting. It could actually be a decent temporary solution while we wait for the fabled patch.
Looking at the list I find myself agreeing on most of your picks, although I have to say that my approach is more similar to @owlbeastmd’s , so here’s my two cents on the topic:
Agree on everything, except Wanderer. I think he’s fine as long as certain other cards get the axe.
Agree with you, but in addition I’d definitely add Flash reincarnation to the list, at very least to Wanderer decks.
Based on my experience actually playing Wanderer Ragnora, and having been able to Flash Wanderer in more than just 2-3 occasions, I feel like saying that the card is definitely more than just an enabler as it really gives a substantial tempo advantage.
Here we have just a different approach to the Rae+Fault+Kha archetypical triplet, and in previous occasions we had the chance to share our divergent opinions.
I would actually go as far as banning only Rae AND Fault, but not Kha.
Fault at 6 mana is just plain wrong, and with Rae they possibly represent one of the worst game killer combos ever. What should be a late game win con, in reality has become a way to shut down way too many matches earlier than it should be. Kha makes it worst, but I’d rather see the Pet and the Spell go between the three.
My opinion here is pretty much the same as owlbeast’s: ban Crescent Spear, Scroll Bandit and Owlbeast sage, but keep Juxtapose.
Again I agree with owlbeast: Xor and Necrotic should get the axe.
If the Mythron would stay though I’d add to the ban Aphotic Drain as it gives too much tempo and sustain to the Trial, and Darkfire Sacrifice in Wanderer lists as it has shown a similar potential to what Flash Reincarnation gives.
Same as you but I’d also keep an eye on Malicious Whisp: true that Vanar got punished the most, we all know that, but this card is just too wrong, and it’s justifiable only because of the Faction’s situation.
Another possibility for the ban could be to create a restricted list like those existing in some vintage MTG formats, limiting the amount of certain cards to 1 or 2 per the deck.
This solution, if not too complicated, could be applied to some cards like Aphotic Drain, Scroll Bandit, Tectonic Spikes, Lucent Beam and Lava Lance, that do represent a potential threat but if relatively hard to draw can be tolerated.
