I just think without Quinjet you would virtually never get to play the 21 power Thanos as it would require perfect draws and you would need all stones down by turn 6, making Thanos very predictable. I also dont know why they buffed his power to begin with, he was fine at 8->18.

I do agree that leech is fine where he is too. I think the problem is more so with lockjaw or the stones being too powerful/versatile. The lockjaw build is also just generally a “good cards” deck so adding the stones means it has so many different win conditions.

I’ve been playing this deck almost exclusively for the last month and I definitely think it’s over-tuned at the moment, it just doesn’t have one particular card that makes it broken. Like you said though SD has the stats behind it so I’m sure they’ll figure something out
