I think get your point. I had similar feelings some time ago when ST wasn’t on the top but I had a pretty good Ethiene deck except when matched against the Big W. I wished I could just ban it.
Yes, you get the point completely. Ozzrel, for example, is a good card that can be played for less points but upset a SK deck. That's fine, there's a level of sacrifice involved with Ozzrell which reduces the value from, say, 13 points to just 5, but it's eaten Dagur so it's a payoff. With Invocation, it kills a boosted Dagur, takes it so I can't resurrect, then potentially plays it with its' own defender R3. Hugely unfair. So if the card's "fine" (presumably because those saying so don't play SK-Eist!), then the game match mechanic is broken and I should be able to 'blacklist' anyone playing Usurper, Ardal and Calveit.
Genuinely think you should be able to blacklist 3 leaders from matchups, but that's a whole other conversation.
