If "Quillbolt Hedgehog" is Special Summoned with its effect, when it is removed from the field while "Imperial Iron Wall" is active it is not removed from play. While "Imperial Iron Wall" is active, if it is TRIBUTED or used as a Synchro Material Monster for a Synchro Summon, it will be SENT to the Graveyard.[1]
This is a ruling of imperial iron wall, you must tribute Quillbolt Hedgehog to activate cannon soldier, mass driver etc. This loop is not legal. Maybe if the card said "send" a monster instead of "tribute" it would be. Why they say this loop is legal?This article should be deleted or corrected.
