yet again, you lot, STOP IGNORING ME! (or at least tell me this is ready for crucible after the challenge has ended, please.)
(PS: By ignoring, i mean, not posting. this topic does have quite a lot of views.)
I fell behind on replying to threads.
+5 attack for 1 turn = +5 damage > 1 spark
1 spark is worth 1 quanta (1 quanta = 1 card)
Each time Light quanta is used Shadow gains more than 1 quanta of value.
Note: With the exception of Solidify, ways that spend Light quanta pay for themselves. So the only cost to reimburse is the 4quanta (3quanta+1card) casting cost.
This makes me think that this card is currently too powerful.
How frequently do you expect Light quanta to be spent per turn? 2-3 times would be my low estimate for the average.
