mtg assembly worker cards Assembly-Worker Foil Mint / near mint condition trading card The Brothers' War preview card:

It's on a list that will never be reprinted and so commands a high premium similar to the Power 9

If you dont have lands or artifacts to give yourself mana or magical energy, other than in rare instances, you cant play other cards from your hand

Rules 02/01/06 Ink-Treader Nephilims ability is mandatory and will create a copy targeting each possible creature whether you want it to or not

Besides under my own control, I once saw this card blow out a player as it was flashed in via an emergency [casthaven]Collected Company[/casthaven] in response to [casthaven]Damnation[/casthaven] as a way to prevent most of the profit for a soon-to-ultimate [casthaven]Liliana Vess[/casthaven]

Its much more fragile once it's in play, but at least a 3/4 creature for 4 mana isnt too bad
