Yugioh question, will this combo work?

Question

If I have Gravekeeper's Servant and Macro Cosmos can my opponent attack? Because Gravekeeper's Servant says "Each time your opponent attacks with a monster, the opponent must send 1 card from the top of his/her deck to the Graveyard. But if Macro Cosmos is on the field it gets removed from play instead, back to Gravekeeper's Servant because it says it must go to the graveyard that means they cant attack right?

Answer 1

yes, your opponent still can.

Answer 2

actually, your opponet can still attack. they just have to send one card from their the top of their deck to the graveyard or in the case of macro cosmos, removed from play. but yes the still can attack

Answer 3

yeah, your opponent can still attack but with marco cosmos on the field it sends it to the removed from play zone instead of the graveyard.

Answer 4

yea they're right. A good combo though is black ptera, cannon soldier and ultimate offering - check it out.
