This is your your go-to low-scale Pendulum in Performages.  You, of course, also have Vector Pendulum or Samurai Cavalry (which of them you prefer is up to you), but Mirror Conductor is a 3-of staple card in the deck because you want to use Luster Pendulum the Dracoslayer's effect to bring another one into play. 
 
In this current format, monsters have low ATK (1850-2500 is considered strong).  While Performage decks are lacking in ATK muscle, it's essential that Mirror Conductor reduces the ATK of opponent's monsters so that you can get over them.  Plus, it's revivable as a Pendulum, it can use the same effect as a monster (for a negligible cost of 500 LP) and it's a LV4 for XYZ plays if needed.  I'm sure, as the Arc V era progresses, we'll get better low-scale options and Mirror Conductor will be a 1-of, but for now it's very good.
 
4/5

Closing the week, we shift from Performapal back to Performage.  Performage Mirror Conductor is a Light, Spellcaster, who is Level 4 (and a 3 on the Pendulum Scale) with 600 attack and 1400 defense.  As is common with the theme, neither stat there is going to win you many contests.  For a Pendulum effect, you choose a Special Summoned Monster on the Field, (this is a target effect) and its attack and defense both become whichever value is lower, even after this card leaves the Field.  That can be cool, especially for bigger Monsters who have gigantic attack but paltry defense scores.  The Monster effect here is similar, but instead of a permanent change to both, you can swap the attack and defense, although this effect only holds until the end of the turn.  You can use the Monster effect during either players' turn however.  You do take a negligible 500 Damage for using this effect too.  This Performage Monster falls about average to me, not bad, not good, honestly I think annoying is the appropriate term here.  Still has uses though.

Finally Friday! Performage Mirror Conductor is a Level 4 Light Spellcaster-type Pendulum Monster with 600 Atk and 1400 Def and Scales of 3. Here is a searchable low scale Performage. The Def is really where it's at since it might become its attack by effect, though not a very high attack. Being a Spellcaster comes in handy if you manage to Special Summon the oldie-but-goodie Arcanite Magician with this and Ghost Ogre & Snow Rabbit. Or you can go the XYZ route into Trapeze Magician or a bunch of other Rank 4 monsters. This conductor has decent stats. 
 
The Pendulum Effect is juicy. Once per turn you can hinder a face-up Special Summoned monster on either side of the field by making its Atk and Def equal to the lower value of the two. It stays that way for the rest of the turn even if Mirror Conductor leaves the field. Its Monster Effect can be activated once during either player's turn to switch a face-up monster's Atk and Def for the entirety of the turn. Then you take 500 damage. The monster effects has one of those minor damage effects to work with the other Performages. All-in-all, the Performance engine is very consistent and we'll be seeing it in competitive decks for a while.  
 
Score: 3.5/5 Manipulation effects come in handy and these can be activated in the Damage Step. 
Art: 5/5 I get mirrors, spell casting, the performing arts, and a baton for conducting. I'm happy.
