The most pool with a single action?

Unnamed, clan impersonated into Guruhi, ousts with a Legal Manipulations bleed using I am Legion and Edge of the World while a Political Flux for 12 has been voted through. So that's 2+1+1+4+12.

Lutz calls Ancient Influence with prey at 1 pool, grand prey at 6 pool, none of these two controlling a vampire, with Political Flux in play for 12, and Khabar: Glory.

EDIT: Add Khabar: Glory.

You can turn Lutz into a Guruhi if you want.
Play Bribes + Voter Captivaion.

That's 1 (bribes) + 2 (VC) + 6 (Ancient Influence) + 12 (first out) + 4 (Edge of the World) + 4 (Khabar: Glory) + 6 (second oust) +4 (Khabar: Glory) = 37.

Add 1 per discipline card on Lutz.

Eventually, if Lutz has turned Guruhi, you might also be playing some Oruns in your deck. If that's the case, say your grand predator calls the AI (which removes Bribes + VC + Edge of the World = 7 pool), you get 2 extra pool per Orun. That's, if you have 11 Oruns on Lutz, a total of 22 + 12 +4 + 6 + 4 = 48 pool. (49, if they play Bribes )

K:G, PI (12) in play. You control Lutz and a Guruhi. Tension in the ranks is in play.

say your acting minion has CEL + POT, and calls the AI.

Your first prey has 1 pool. She blocks. in the combat, you play Torn Signpost, Hand strike, Pursuit for an additional strike, Torrent, Disarm. That's 12 + 4 pool. Play Edge of the World to cycle.
New prey blocks. Repeat for 10 pool.
No other blocks.
Your prey is ousted by Ancient Influence - 6 (oust) + 4 (KG) + 1 (Bribes) + 2 (VC) + 6 (AI)
Your new prey is ousted by Lutz (6 + 4).

You've won 20 + 10 + 19 + 10 = 69 pool.
Sadly, there's noone left to witness it
