hmm ...
or
... but I'm not sure which one just yet.
I don't remember if the metapower reduces the
overall cost
or only the
cost of the metapsi.
Your example is 1+1-2 = gold.
Otherwise 1+(1-2 limit 0) = 1 ; still rather juicy.
If so, this would generate a slowly expanding geometric (!) loop.
Still needs the clunkier 1pp version of Sychro.
Midnight Aug can reduce 1pp for 1 essentia point, but only after 1pp Aug has happened.
This would get the 3pp Aug version of Sychro going.
And with Metapower it's down to 1pp.
Just one more reducer needed for TPK of the world.
