Design Notes
"Sufficiently Advanced M. Maestro - Quantum Machinist" has nearly the same name as "Sufficiently Advanced M. Maestro - Cryptic Mech". Additionally, it has the attribute, level, and original stats of Dark Sage, while Cryptic Machinist has the same attribute, level, and original stats of Dark Magician. The previous names "Cryptic Machinist" and "Quantum Machinist" were meant to evoke the same sense of name as "Dark Magician" and "Dark Sage" in the same way all Advanced M. pairs are meant to evoke the name of famous Spellcaster monsters throughout the series. The current names of "Cryptic Mech" and "Quantum Mech" are a slight retreat from this previous position to enable "Sufficiently Advanced M. Maestra - Cryptic Mechanist" to have a longer name in the manner of Dark Magician Girl.

Quantum Machinist is the only "Sufficiently Advanced" Ritual monster to have a level two higher than that of its listed precursor monster.

It can be summoned in conditions similar to those Dark Sage, though it is not limited to being summoned in this manner, and the conditions are described on the precursor monster instead of itself. In a reverse manner, summoning Quantum Machinist in this manner requires the player to have the precursor monster destroyed in a manner that leaves the user's field empty, as opposed to using such an effect on the opponent.

Effect
Quantum Machinist has a form of built-in protection, but it is required to have been Ritual Summoned and have been kept face-up to obtain and maintain use of its activated effects. This prevents some easy manipulation, such as with its own effect resurrecting another monster and then tributing and resurrecting itself, or refreshing such as with Book of Moon.

The effect of Quantum Machinist features the same sort of ability as Cryptic Machinist has, to tribute the opponent's cards as the cost to activate an effect. Whereas Cryptic Magician must target the tributed card (and so is prevented from tributing cards that cannot be targeted, such as Quantum Magician) and necessarily requires you to have at least one other card in your possession, it has a bit more latitude in some ways, in that it can target any type of card for tribute, including a Spell or Trap card, and can add a card from the deck to the hand. However, its effect can only be activated once while it is face-up, and only adds or returns cards to the hand.

For comparison as to the effect's length, "Chaofeng, Phantom of the Yang Zing" has an effect past 7 lines (with a more awkward justify, albeit) in the standard template's margin in visual edit mode if you exclude its Synchro material text line.

Strategy Notes
Quantum Magician can be very powerfully augmented regardless of which Sufficiently Advanced Ritual Spell is used to summon it.
