Face down enchantment on illegal target, is it legal?

[rodriguekhalil]

I saw some topics related to the subject, but none, to my knowledge, that answer that very specific question (let me know if I'm wrong please):

Can I put a face down enchantment on an illegal target? (Bear Strength on a non-living creature, Harmonize on an object without channeling, eagle wings on a mage, etc.)

From what I understand, if I reveal the enchantment and the target is illegal, then it is automatically destroyed. However, as long as it's face down, this shouldn't matter, right?

Then, I can use Shift Enchantment or Enchantment Transfusion to put it on a legal target before revealing it.

Also, related question: What if Sersiryx or Sectarus casted a non-curse spell (decoy or anything else.) I guess it would, again, be destroyed when revealed, but as long as it's face down, it doesn't matter.

Why would I do that? To play a mind game against the opponent, of course.

Thank you,

No.
Step 1 casting a spell requires that the target be a legal target of the hidden enchantment.

Shift and enchantment transfusion also require the recipient to be a legal target so you cannot move a hidden bear strength onto a zombie for example.

Kharhaz is correct. Purposefully casting an enchantment on an illegal target, or from an illegal source, is cheating.

    Makes sense,

thanks guys.

yeah, great question.
And good answer offcours.

Because I had read something about playing a card face down to bluff on your enemy.

And I was playing with the idea of putting a bear streng to play as a trap. To place it in a zone and than shift it to my creature before attacking.

But that is also incorrect than I gues

But you could put an enchantment on a legal target, even if you could never reveal it on that target?

Like [mwcard=MW1E23]Jinx[/mwcard]

Yes, you can put Jinx on a creature like Iron Golem that can never cast a spell.
