Just to note:
1) Hata is on Vacation. A well deserved vacation. Out of respect for his need for a break, I will not be discussing anything UFS related with him before he returns to the office. Any ruling / clarification / errata / etc. in a situation like this has a ripple effect throughout the entire game. Something with a ripple effect as strong as the requested actions in this thread I MUST discuss it with James before proceeding. Hence my overall silence on this for the time being.
2) On the Hatman suggested errata, it would actually have to read as follows:
F Commit: Draw 2 Cards.
The following response may not be negated or canceled, and may not be responded to.
R Discard 1 card: Negate this cards's F ability. Playable while commited. Only playable by your opponent.
