I block w/ The Strength Within. My opponent attacks again and enhances w/ Perfect Memory. Can he use the enhances on TSW? I assume he'd have to be playing a character w/ Fire to use the second (or have a POTM in play). But can he even commit his attack for the cost? The current AGR suggests the answer is no. Egyptian Temple and the Golden Rule suggest the answer is yes.
2.8.1 Cards can’t be in more than one position at once. Cards that are in out of play zones, the card pool, or are attached to other cards do not have a readiness state and cannot be committed or readied.
I was hesitant to rule either way yesterday, as I can see arguments for it working both ways.
Possible followup question, if you can commit an attack in this unlikely situation, and then used some Taki Support to move the attack to your staging area as a Face Down Foundation, would it retain it's committed state? Here I'd be rather inclined to say yes, even though it's kind of becoming a new card... on the other hand it is forgetting that it was an attack so it could be argued that it also forgets it's commital state.
