Quick question, easy answer no doubt.
All of the QoD "hatchling" cards say something like "If you control Dragon X, attach Hatchling Y and all of its duplicates to Dragon X as duplicates."
Does this mean you can play the hatchling from your hand to that dragon as a duplicate? If so would this be a marshalling action as per normal duplicate rules?
Whether or not you can attach from your hand does this mean that dragon X can potentially have 5 duplicates (2 more dragon X and 3 hatchlings)?
Thanks
