phyrexian metamorph and token doublers

So im brewing a [[Hashaton,Scarab's Fist]]deck at the moment and i was to slot in a [[phyrexian metamorph]] so i could make more copys of [[monument to endurance]] and i was wondering if A: if i discard metamorph and made a token would i still get to pick to have it enter as a copy of a artifact or creature B: if i have a token doubler on the battlefield such as [[exalted sunborn]] would i get multiple copys of the monument or would they just enter and copys of metamorph i apologize for the possibly dumb question i just cant seem to get google to cough up the right answers
