Depends. Does it target the creature? If it does, then no. Shroud means it can't be targeted by spells or abilities - even your own.
Fluttershy is best pony.
Can you equip something to a creature you control with shroud? Or do those fall under the catagory of spells/sorcery/instant and can't target...
equipping targets, so you cannot equip a creature with shroud.
although with a card such as Stonehewer Giant you would be able to attach equipment event to a shrouded creature
Indeed. Only using the equip ability targets, the actual act of equipping doesn't.
