Forum:Super Poly vs. Light Pulsar + Red eyes darkness metal

I was dueling my friend recently and he used super poly to summon five headed using my light pulsar and red eyes darkness metal. Does light pulsars effect still activate where I can bring back a lvl 5 or higher dark dragon which in this case was red eyes? He told me i couldn't because of something about light Pulsar's effect interrupting five headed's summon.
