According to the ability of *Jedah*
E Commit 1foundation: If your attack deals X damage, during your End Phase, add your attack to your staging area as a foundation. This attack is considered a foundation while in your staging area. X equals your attack`s printed damage.
1) In relation to this, I can commit these attacks in my staging area as if it go foundations to help to pay to the control check ?
2) At no moment it says that they go face down or cards in blank, reason why even its difficulty and control check, block modifier, for effects of other letters?
Thanks.
