The copy is created on the stack, so it's not "activated." Creating the copy won't cause abilities that trigger when a player activates an ability to trigger
You both have a deck for a game of Jumpstart
If youve managed to discard your opponents hand, this shouldnt be an issue because its less likely they will find the stuff they need to utilize their added Ink anyways
If you have some counters and some mana, it makes combat anywhere difficult for your opponent and lets you pick off utility creatures, and the base stats help give you time to grind out an advantage with this kind of thing, especially if you have a lot of evolve or scavenge to keep it fueled
