[confirmed]Morph vs. Can't Cast

[Korath]

Describe the Bug:
The AI's Iona, Shield of Emeria with Red chosen prevents me from casting Blistering Firecat face-down.

Which card behaved improperly?
The problem's on the can't-cast side, not the morph side. I think.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Dev 2bba4ec.

What exactly should be the correct behavior/interaction?
707.4. Objects that are cast face down are turned face down before they are put onto the stack, so effects that care about the characteristics of a spell will see only the face-down spell's characteristics. Any effects or prohibitions that would apply to casting an object with these characteristics (and not the face-up object's characteristics) are applied to casting this object. The permanent the spell becomes will be a face-down permanent.

Are any other cards possibly affected by this bug?
Everything else that prevents a player from playing a card with specific characteristics. (And the non-creature morph cards - Lumithread Field, Whetwheel, and especially Zoetic Cavern - will need to be kept in mind, too.)

Also happens with split cards - i.e., an Iona set to red prevents me from playing the Ice half of Fire // Ice.

I confirm also the "can't cast" to split cards.
