There’s a reason the theme deals with ATK and not Levels

Materials: 2+ Level 1 monsters
You can only use this card name’s (1) and (3) effects once per turn each.
(1) If this card is Xyz Summoned: You can send 1 “Drytron” card from your Deck to the GY.
(2) If you would Tribute a monster(s) for a Ritual Summon, you can detach the appropriate Xyz Materials from this card instead.
(3) When an opponent’s Spell/Trap Card is activated while you control a Machine Ritual Monster (Quick Effect): You can detach 1 material from this card; negate the activation, and if you do, destroy it.
Note: This card’s name seems to taken from 42 Draconis, a star named Fafnir. μβ’ is apparently the numerical spelling of 42 in Greek. Though it would be more normally written ΜΒ´)
