I think White Fur Guard is probably good, but probably not OP/Super Sayan 😄. A 4/5 stat line is much preferred - especially on defense-oriented frontliners.
I do agree that LV has made the game feel more P2W. I paid to have 2x blades before they exploded, but they are in most of my decks. There are only a few decks that arguably don't benefit from them or can get by without them (CDM and combo magic come to mind).
BUT I mentioned in my article: buffing these 4 and 5 drops is an indirect nerf to Blade. Alternatives to Guild Enforcer that can't be "Bladed" will start to find their way into more decks.
Makes sense, but feels bad they created a problem and now need to go around it, but like you said in your post they know future cards we don't. Maybe this is part of a bigger plan 😆
I am thinking on White Fur more on Agro decks than control tbh.
The thing is War going first is a pain already, by the time you get to 5 mana and drop this will be hard to remove it imo, if it sticks in the board and soul survivor next or give it any other big buff is most likely gg. On other hand almost F2P war is a thing at least.
I would love to see epic cards from MJ being cared as such, feels bad Rare cards are better and common cards getting those big buffs
