I still think wanderer is fine. Its basically a tempo deck that has to keep board until it can pump out wanderer, and when it falls behind it really falls behind. The reason why everyone says it is highroll is because while it is relatively consistent due to the neutral options allowed it, it still is not as consistent as a non highlander deck, ending up in the inevitable questions “do I have the right answer?” “Do I have the good tempo turn?” Without the answer to both of these being yes, the game gets much harder for wanderer.
The reason why it may hurt to lose to is because when wanderer wins it generally wins hard because it has no powerful single win condition to run you over, but rather it slowly snowballs until it steamrolls you because it is a tempo deck with much stickier stats. BUT IT IS SLOW. Or at least it can be. Instead of focusing on whats in the opponents hand, focus on the opponents board. Clearing threats and setting up your own is the way to beat wanderer. Take board early, and it is much harder to lose your own advantage. Clearing board or aggressively focusing on face before wanderer can go off while keeping an eye on the mana tiles is how you win. It is not broken, it just requires the right calls and knowing what the wanderer wants to do NOW.
I rarely call nerfs on anything because in my experiences, there has been a LOT worse that deserved the biggest hammer, or even just slightly worse that ended up being fine and healthy.
Wanderer loses, Ive seen it, Ive beat it, and I dont care about it.
Now apex, that is pretty scary.
