If "Macro Cosmos" or "Dimensional Fissure" is active while "Imperial Iron Wall" is active, cards that would be removed from play when sent to the Graveyard are sent to the Graveyard instead.

It does cause a chain however Macros effect is not a cost and hence only has to be obeyed until another effect super-cedes it, i.e. if a card says this card can not be removed from play (Miracle Jurassic Egg) even if Macro Cosmo is on the field it can not be removed from play by cards like Dark Core.

Point is Since Macro's effect is not a cost it can be over-ridden.

Imperial Iron Wall's effect is:

Cards cannot be removed from play.

Macros Cosmos' effect is:

You can Special Summon 1 "Helios - The Primordial Sun" from your hand or Deck when you activate this card. While this card is on the field, any card sent to the Graveyard is removed from play instead.

I think that it would be just a loop that doesn't end, unless someone uses a Trap or MST to destroy at least one of those 2 traps.

That would be the only way to solve the problem. If this doesn't happen, then a card CAN'T be sent to the graveyard because of Macro Cosmos and a card CAN'T be removed from play because of Imperial Iron Wall, resulting in a loop.

Imperial iron wall was destroyed. So it goes to the grave. But since macro cosmos is on the field its removed instead

imperial iron wall beats macro cosmos and the cards go to the graveyard and if imperial iron wall gets destroyed then it goes to the graveyard

general knowlege

Ok First look at the effect of "Impereal Order"

As long as this card remains face-up on the field, negate the effects of all Spell Cards on the field. Pay 700 Life Points during each of your Standby Phases. If you do not, this card is destroyed.

Ok this trap card negate the effect of all spells(become like they dont have any use)

So the monsters sent to the graveyard because the effect of Macro Cosmos Negate

Hope this helps

Opus,hehehehe Sorry i thought it was Imperal Order ^_*

it is send to the graveyard

imperial iron wall will get over macro
