I'm having some trouble understanding the interactions between Ixidron and Infinite Reflection.
If I enchant Ixidron with Reflection, do my face-down cards stay 2/2s? Are they even considered copies of Ixidron at that point?
If I have Ixidron turn a creature enchanted with reflection face-down (say from playing any creature with an enchanted Ixidron already out), do all my creatures become 2/2 with no abilities? Do they still have the name of the enchanted creature? Are they considered face-down?

They will be face-down 2/2 creatures that have Ixidron as their front side. There's no morph cost to reveal, so you can't "unmorph" them.



Turning the creature enchanted with Infinite Reflection face-down doesn't have any immediate effects. It won't change the characteristics of any creatures already on the battlefield (except, of course, that particular enchanted creature). So the copies of Ixidron will stay copies of Ixidron. However, any new nontoken creatures you control will enter the battlefield as copies of "2/2 creature with no other characteristics" (so no name, color, abilities, creature types, etc.). This effect doesn't mean that they're face-down.

Thanks. You can be assured that this knowledge will not be put to any use that can be considered "good".
