When I was playing yugioh dueling nexus I wanted to make a venom deck but when I played starving venom fusion dragon it still lost attack and defence from venom swamp. The card does not say its not treated as a venom monster so I was confused on why it was still effected by venom swamp can someone tell me why? i didn't use its effect either. they negated it with skill drain.
