C Common Vehicroid Connection Zone X SPELL Fusion Summon 1 "Vehicroid" Fusion Monster from your Extra Deck, using monsters from your hand or field as Fusion Materials, and if you do, it cannot be destroyed by card effects, and its effects cannot be negated
I think this issue has been addressed in previous threads, but in general, I look at it THIS way: Structure of the card physically changed in some way, other than trying to bend it back out or flatten a dent (good luck)
So, if your opponent cant defend their sites, this powerful interaction can deal serious damage to your opponent
Psychic Venom was clearly a menace in the early days of Magic, especially when combined with tapping effects like Icy Manipulator, Twiddle, or Power Sink
Must first be Special Summoned (from your hand) while you control no monsters
both will consume your opponent's monster for your fusion summoning
