by the way, does anyone have any thoughts on the rule changes, or does everyone like them?

The fact that the battle takes place strictly in the teleport is implied anyway, but writing it in the rules to avoid misunderstandings would be helpful. If you decide that it's not strictly in the teleport, then that should also be reflected in the rules, and then the nuances related to this will be clear.

The other clarifications in the rules are also good and I think they are useful.

Necromancer is good even without a Transformer, as I see it, I probably won't give it to my opponent.

The clarification regarding the battle time (up to 1-2-1) is also needed.

I'm not sure what the difficulty setting affects here, so it seems unimportant.
