This card can't fit in a mono-deck of any kind. Running mono
with 6 Quana Beasts and 6 Novas to buff them or Quantum Pillars/Towers won't work. A creature buffed according to the amount of quanta you have is mechanic-wise similar to Dissipation Field, so it is going to work well in the same decks Dissipation Field works well. And the kind of deck DField best fits in is Quantum Pillar/Tower-based rainbow.
I think 6
can be kept, but a much more expensive
cost would be better.
If you don't want it to become another
deck buff, then put "X is the amount of
quanta you have divided by 10" or something...
