Vylon Delta fits well in a Morphtronic deck because they are able to easily summon level-7 Synchros through Morphtronic Scopen. And also have monsters that benefit from equip cards like Morphtronic Videon and Power Tool Dragon.
Way too slow. Plus Vylon Cube would be a much, much better Tuner than Junk Synchron unless you really think Junk Berserker is worth it. (Actually, Berserker's significantly better in Noble Knights anyway since it's Warrior.)
