Is it possible to derez Cold Site Server with Warm Reception and thus save the power counters from being removed? I believe the Corp player gets to order start of turn effects however they choose, but I'm not sure if derezing Cold Site after the effect has already been queued so to speak would prevent it from happening.

Yes, I think you can.

With Red Level Clearance or Key Performance Indicators you can effectively fast-advance agendas. The discard 3 to rez "downside" of Plutus is mitigated by powering up Logjam and Armed Asset Protection.

also if you trash three transactions (and can protect it for two more turns), the downside becomes an upside (since you're playing those operations clicklessly with Plutus, unlike if you'd played them from HQ).

KPI can NA a 4/2 with Plutus, but not FA anything like RLC can, no?
