Confirm got wrong stuff here.
1. You CANNOT use super fusion to summon chimeratech fortress ever
2. Fusion is not a cost correct, but this is not a fusion in the first place. This is only a special summon. Look below......
Chimeratech Fortress Dragon
[Cyber Dragon] + 1 or more Machine Type monsters
This card cannot be use as Fusion material monster. This card cannot be special summon from Fusion deck outside of by sending
the above cards from the field into Graveyard (The Magic card [Fusion] is not required). This card's original attack strength
is equal to number of Fusion material monster x1000.
So once he declare, its straight away sac one. Like bloo-d. Hence, no chaining no funny business. Otherwise how people can just sac away ladd while I have a dna surgery and a proto cydra on field. If still dont understand, time for you to laugh at yourself liaoz.
