Most of the time, i can unleash a SN-Precog chain in turn 1 ~ 2, ends up with 6 or even 8 Quanta overall.
Sure - If u get 3 High cost-Critters with your 1st Shard, thats just bad luck.
I think its not about having quanta to play all the cards u get right away, but use the best card at the best time.
U can get out A LOT of nasty Combos. If im low on Quanta, i not even play a shard, it would juz clog my hand.
Atm i do 1 HG/ 1 QT . my stats so far: 40 / 0 ^^ vs AI3
