After the spell functioned. there is no quanta production the next turn.( So it makes sense.) Quanta production will start BEFORE playing any cards... Also Expected number of pillars is 8... that means you can't play this card until you have a total number of 8 pillars and pendulums above in play.
You misunderstood again. (reminds me to check back on cards even without updates)
I meant for you to estimate what you expect the number of pillars to be. Then put that number into the formula. (if you estimated 8 then it would be 8-4=4|8-6=2) Then you put the result as the casting cost. (if you estimated 8 then the casting cost should read 4
|2
).
The card is able to be played whenever the player can pay the casting cost.
(if you estimated 8 pillars then they could play it if they had 4
|2
and were not silenced)
