How about this:
It now acts like a pillar or tower stack, making it vulnerable to earthquakes. Essentially its a pillar that produces no quanta, but transforms into pillars of the type you want. Since it is a stack you are guaranteed to only be allowed to make 1 pillar a round (or 1 pillar and 1 tower if uppgraded version is used too).
In essence the trade off is
-Slower speed
-Higher versatility than other pillar types
-Greater long run production than single quanta pillars
-Moderately improved resistance to earthquakes over other pillars
-More reliable than quantum pillar, but slower production rate
In short, it can supplement quanta production and round out shortages of a few quanta types but decks will still want standard pillars or alternate quanta sources to tide them over in the short run.
Income breakdown using these + mark only. Assuming you get 4 (EOTQ = End Of Turn Quanta):
Quanta Production:1 |1 |2 |3 |4 |5 |6 |7 |8 |9
EOTQ :1 |2 |4 |7 |11|16|22|29|37|45
Now suppose you get 1 construction and 3 standards + mark
Quanta Production:4 |4 |5 |6 |7 |8 |8 |8
EOTQ :4 |8 |13 |19 |28|36 |42|50
Compare to previous analysis from OldTrees for 4 standards + mark
EOTQ:5|10|15|20|25|30|35|40
This is lower production until after 4 rounds. After the 5th round it actually overtakes standard pillars only.
But, whereas you will be stuck with whatever types you draw using standards, you will be able to direct your quanta production to match the other cards you draw.
So the question is: Does the increased versatility, and long run benefit make up for the reduced production rate at start.
