I agree with @improbableblob in regards to positioning. It matters a lot and always will. And this also ties into what @niklaren and @owlbeastmd talk about that the Mantra or Artihai decks aren’t as uninteractive as people think or claim. There are a lot of important and subtle decisions to make which are not that obvious to the opponent because it rarely happens on board. But that is not uninteractive. I would say the only uninteractive decks were the DDoS decks. Skipping your turn is uninteractive
And @1pancakess is right too, not Wanderer itself is the problem, the stuff around it is (e.g. Flash). Wanderer is a great concept and brings a lot of unused cards back on the board. Everybody is also able to add a little bit flavour too with all the 1 ofs which is fun in my opinion.
