I just beat Klaw (standard with Masters of Evil) using Black Panther / Protection in solo play and this was a close one. It was very fun. However, I managed to do it while making a specific tactical choice and I wondered if this was truly legal. I happen think it is, and therefore I haven't "grim ruled" it, but I thought I'd ask here, just in case I have to put an asterisk next to my Win column.
During an encounter while Klaw was Stage I, I happened to reveal The Immortal Klaw side-scheme. I added his 10 hit points as required.
Considering that I was maintaining good control over the main scheme, which was still at 1B, I believed I was able to stomach the increased threat for a while. Therefore, I proceeded to kill Klaw instead of getting rid of his side-scheme.
I managed to do it. When he flipped to Stage II, his text reads: "When Revealed: Search the encounter deck and discard pile for The "Immortal" Klaw and reveal it. Shuffle the encounter deck."
Since the side-scheme was already revealed, I didn't do that, but I did shuffle the encounter deck. I presume this does count as a change in game state.
Now, Klaw II starts at 18 hit points, but since I've already added the +10 from the side scheme earlier, I didn't have to add anything at this point. On my next turn, I thwarted to remove the side-scheme, which made Klaw lose 10 hit points. He was now at 8 hit points. Which enabled me to kill him on my next turn...
Is that legit? I cannot see why not...
