Prerequisites

• THE SPELL'S TWO HALVES READY TWO DISJOINT SETS, WHICH IS WHY FIORA DOUBLES IT RATHER THAN OVERLAPPING IT. Half one readies every ALREADY-BUFFED friend by spending its buff. Half two then buffs 'all friendly units' — and 702.3.a means only the ones with no buff receive it, which after half one is exactly the set half one could not touch. Every unbuffed 4-Might body among them crosses to 5, 709 fires 'becomes Mighty', and Fiora readies it for 1 Order Power. One spell, both halves of your board upright.
• 703 gives the buff +1 and 708 sets the Mighty line at 5, so the second half only converts bodies sitting at exactly 4 — a 3-Might unit reaches 4 and stops, a 5-Might unit was already Mighty (709's own second example). The first half has no such condition: it readies any buffed unit whatever its Might.
• Spending a buff is what half one costs, and that is a payoff elsewhere: SFD-101 Fae Dragon's 'When you spend a buff, play a Gold gear token exhausted' fires once per buff spent, which is the catalogued overt-operation-fae-dragon-industrialist. This entry deliberately does NOT declare the Dragon — the claim here is the double untap, and adding a fifth card would force the matcher to require it.
• Five Energy and 2 Body Power for the spell, three Energy for Fiora, then 1 Order Power per body the second half readies. Both Power costs land in one Main Phase, which against #44's free floor of 2 Power a turn is the real constraint: the spell alone is 2 Power before Fiora is paid at all.
• Three uses a game (103.2.b) and it is an [Action], so 806.1.b lets it be cast in a Showdown as well as your Main Phase — readying a garrison mid-Showdown is what separates it from peak-guardian-fiora-mass-ready, which is a unit and can only be played in an Open State.
• It readies, it does not protect: everything it stands back up is still whatever Might it was, and Fiora is a 3-Might body that the opponent can simply remove first to switch the second half off.

Steps

1. Play Fiora, Worthy (3 Energy) at any point beforehand.
2. Spend your units' exhausts as normal — move them, attack, pay exhaust abilities.
3. Cast Overt Operation (5 Energy + 2 Body Power). First half: for each friendly unit that carries a buff, spend that buff to ready it.
4. Second half: buff all friendly units. 702.3.a places a buff only on those that have none — which is now every unit half one just spent, plus everything that never had one.
5. Each unbuffed body at exactly 4 Might goes to 5 and 709 fires. Fiora's trigger goes up once per body: pay 1 Order Power each to ready them too.
6. Both sets are upright, in one spell, in the middle of your Main Phase or a Showdown (806.1.b).

Per iteration
