Only 6 pendalums to power this deck? I wouldn't be surprised if this were quanta starved, even with the rustlers.
6 pendulums, powers either 6 life quanta or 12 life quanta per turn. -.-" That would give an average of 9 quanta per turn, making the QI 7.1111 (to 6 s.f.), which means you will be very quanta starved. The other version replacing the scorps with 3 pens and a heal has a QI of 4.07407 (also to 6 s.f.). you will have too much quanta that time.
I would say 8 pendulums, 6 adrenalines, 6 horned frogs, 6 rustlers, 4 scorps, giving a QI of 4.5, a overquanta, or 7 pendulums, 6 adrenalines, 6 horned frogs, 6 rustlers, and 5 scorps, giving a QI of 5.42857 (to 6 s.f.), a little underquanta. If you want, in the latter change an adrenaline for a jade staff.
