There are very few mechanics in MTG that are outright hated
Each of them has various levels of value
Assassin's Trophy is a nice addition to the sideboard, but it isn't 100% necessary if you are trying to upgrade on the cheap, and the same is mostly true of Leyline of the Void (which is probably no longer optimal now that Rakdos / Jund Sacrifice is on the downswing)
The holo cards could be kept in toploaders and displayed or even kept in a toploader binder
Betor steers the Abzan to embrace their independent aspirations while ensuring they are aligned to the collective good
I wonder if these remastered sets count as having been on a plane, because if thats the case, itll be a good while until we go back to Ravnica, and theres quite a few commanders I would have loved to see in a retro or anime frame like Circu, Dimir Lobotomist or Prime Speaker Vannifar
