Sorry I can't match up with your enthusiasm on this matter
let's just get it over with
COMBO (Fire Punch + Focus Punch) - cooldown - COMBO (Fire Punch + Focus Punch)
[THREE SUBS]IF Fire Punch is disabled OR Focus Punch is disabled OR Deoxys has less than 24 en A3 THEN COMBO (Giga Impact + Knock Off) A3
Handbook reference: This is the minimum amount of energy the Pokemon needs to execute the combo. If it has less, the combo fails and the Pokemon faints from exhaustion. If the combo is a same-move combo, the base energy cost is the cost of using the move on that action and the following action, with all modifiers like STAB and consecutive use penalty factored in. If the combo is a different-move combo, the base energy cost is the cost of using one move on that action and the other move on the following action, with all modifiers like STAB and applying consecutive use penalty to whichever move (if either) was used on the action prior to the combo.
Fire Punch + Focus Punch uses 24en, meaning 24 are left. Fire Punch + Focus Punch used one after the other use 24 en, so it should make the cut exactly. Since the fail happens only if Current en is lower than Base Energy Cost (not if it is equal) it should work.
