HELLO! This is interesting. Solid sounds nice and, well, solid! *Laughter*
For the summoned creature suggestion, how about a life/earth duo, seeing as it generates those two elements of quanta. It might generate either of:
Leaf Sprite | Root Sprite
2|2
0: Sacrifice to give +2|+1 to target creature.
Dust Sprite | Soil Sprite
1|3
0: Sacrifice to give +1|+2 to target creature.
It might stack so you could only use the ability once, just so that it wouldn't generate 6 Sprites a turn.
Issues?
