Polymerization

if a card like D. Fissure and Macro are on the field, cant you still use Poly? or Superpoly?

Yes,... but don't ask me why..
even with super poly text that specifically said send to grave


(But morelikely because sending is happen on resolution, not cost)

yes you can use them because the sending to grave part is part of the effect, it's not a cost so the monsters will just be removed/

Cost/Effect is why.
