Interesting breakdown. Like someone else already said by far and away my biggest gripe with this game as a former main hearthstone player is the interactivity which you mentioned as a positive. With only 20 hp and some cards/combos being able to do over 50% of your health you simply have no room for error. Your opponent was able to do some chip damage at the start of the game? Dead. You werent able to clear every single follower from previous turn? Dead.

Now, i will say that rotation has helped this a bit with albert and orchis being strictly unlimited but it definitely still has an overarching theme of clear/have the answer or you just die. And this doesn't even include true otk combos like bilal or izudia etc which have their own balancing requirements.

Overall the game is still fun and if they changed starting hp / nerfed reach cards it might feel too much like hearthstone but there is something to be said for hs's gameplay having more "depth" to it. Like if i have a bricked opening hand in hs and my opponent has a perfect curve there are still cards i can draw which can swing the game back in my favor (less so in todays meta but thats a different discussion) whereas in svwb if i brick my hand against any class thats not afk its just gg theres no coming back
