This card to work well needs:
+6 creatures on the field.
Flooding.
To satisfy these conditions you have to have:
A 4 cards combo (SoP, Flooding, a creature and a spawner card like Mitosis or Fractal).
A huge amount of quanta: to play spawner, to play creatures, to keep flooding active.
To be delayed for 1 turn
At least one turn more to compensate turn of delay (with low Atk creatures, that means not high damage in any case)
And it isn't an OTK combo, not even a perfect draw. Many others combos deal more damage of this in less turns.
Moreover, it's very easy to break with:
Quanta Denial.
Creature Control.
Stall cards like Phase Shield.
Too much cards, slow, fragile and not so effective too.
