Shroud prevents a permanent from being targeted by any spell or ability, regardless of the color, type, cost or source of the ability. And while aura enchantments do target when cast, they is nothing that prevents a permanent with Shroud from having an aura attached to it.
Can you equip something that has shroud?
If you equip your creature with the cloak, it will have shroud, so you will be unable to activate any more equip abilities targeting it until it no longer has shroud. So yes, you need to unequip the cloak before you can equip your creature with that Trusty Machete.
What is Hexproof vs shroud?
Hexproof means that it can’t be the target of spells or abilities your opponent’s control. Shroud means that it can’t be the target of anyone’s spells or abilities.
Can a creature with an aura be attached to another creature?
Yes, they certainly can. In fact this is a famous counterintuitive loophole (or we can be polite and call it a “quirk”) remaining in the tidied-up modern rules. ETA: Initially I thought an Aura might even be able to come into play attached to a creature with Protection from that Aura’s colour (before falling off again as a state-based effect).
Can a card enchant a creature with shroud?
An Aura’s target is specified by its enchant keyword ability (see rule 702.5, “Enchant”). If the aura is entering the battlefield due to some ability or spell just putting it there (like Starfield of Nyx’s triggered ability) you can put it on a creature with shroud, because the aura is not on the stack, therefore it doesn’t target.
Can a Genesis Wave enchant a shrouded creature?
If an Aura is placed on the battlefield using Genesis Wave or an ability like Sun Titan’s, can it enchant a creature that has shroud (or an opponent-controlled creature with hexproof)? I’m looking at these rules specifically: 303.4a An Aura spell requires a target, which is restricted by its enchant ability.
Can You enchant a player with a 303.4 aura?
Yes, they may. The cards you mentioned returned those Auras to the battlefield, so only 303.4 applies here. It should also be notes that the aura must enchant a legal object (i.e. Auras with “enchant player” must enchant players, auras with “enchant a creature you control” cannot enchant noncreatures and cannot enchant opponents creatures, etc)
