Though sometimes it's the other way around.
I remember once playing 2 quantum towers and 1 time tower (+ time mark)... and playing a pharaoh second turn ;P
This means my mark and tower generated 3

, while quantum towers generated 6

out of 12 total quanta they produced.
Sometimes I can play a permafrost (7

) before I get a single

to play a fog shield, though that happens really rarely.
As for decay, yes... pests seem to dislike

. The last time I fought him I had only

and

quanta remaining for a number of turns, but I finally managed to cast a plague and a quinted pharaoh in the meantime.
