Quote If a card in your Pendulum Zone(s) or a Spellcaster monster is targeted by your opponent's effect: Target 1 Wyrm monster you control that would be an appropriate target
Special Summon this card, and if you do, this card gains ATK equal to that monster's ATK
Though not all Magicians can really do it, I think it is Destruction Magician that has a Scale 3 iirc, and the effect might end up screwing you over if you needed X Magician Pendulum to be drawn and used as your Scale, only to end up Summoning it with this card
This will give our network slightly more data to work with allowing our model to generalize better
