ok...if i use future fusion for say a chimera tech over dragon.
say i used 10 machines and 1 cyber dragon.
and now say 3 of those 10 monsters use for future fusion were Cyberdark keel, cyberdark edge and cyberdark (the other 1) for cyberdark dragon.
can i use overload fusion to fuse them to make cyberdark dragon and still the cchimera techwill come after 2 turns?

yes i know that chimera will blow up everything when it is summoned but itsurgent.
need answers!!!
