Stealth Astral and reverse-communion

[Finalgenesis]

Just a quick Q, does stealth astral intercept mind hunts if it was in enemy provinces? eg. enemy mind hunts an enemy province which just so happen to have a star child or two on it, will you counter attack and fumble their minds?

For reverse communion, I understand that if you go the matrix route you can bring certain master's item effect to all the slaves (Crystal shield) as it is "cast" at the very start of battle when you are already in communion. My question is, are summon items such as wraith crown, bottle of water, bag wind ...etc also coded as "cast" (summon water ele, undead horder spells ...etc)? Can you bring in a 4 master +12 slaves all matrixed up, with each master wearing a bottle of water and thus having every slave spawn 4x water elemental?
