Looks powerful to me. Some ideas:

Install-advance-advance Mandatory Upgrades/Vanity Project, advance-advance-advance-advance-score in the next turn.

Play 2/4 Agendas in never-advance decks.

Use Melange Mining Corp/Eliza's Toybox and then do something, like installing a card or playing a Hedge Fund.

So purge viruses and do something. Very potential card.

Does it have to be the exact same action three times or does this still trigger after click-abilities of different cards? Like Jackson, Jackson, Private Contracts for instance.

Another thing: Can i combine a double operation with a regular one to get the forth click?

I believe this only works with single actions that cost 3 clicks, not using three clicks to do the same action 3 times.

So, that would be Melange, Purging Virus Counters, Domestic Sleepers, Eliza's Toybox, etc.

From FAQ 3.1:

67 Jeeves Model Bioroids
• Playing a double operation and then playing a regular operation,
spending three clicks for Melange Mining Corp., as well as clicking
for three credits are each considered spending three clicks on the
same action. Additional [ costs are still costs to trigger an ability.

So, "same" action is considered action that bears the same common type - playing operations, installing, advancing, etc. Paid abilities however should have the same origin, i.e. card.
