The +4 damage on your NEXT attack is not worth it. Card draw is pretty scarce and having an extra card is worth much more potentially.
The attack is ublockable, provided you have 6 energy essentially, making sure that when you pay for your attack you have at least a kick and a punch left over in your energy. THEN it is unblockable.
Much better way of making your attack ublockable and at the cost of 1 and to set it (usually on a previous turn) to set you up for an explosive finish.
