If i control Ardenn, Intrepid Archaeologist and a Grafted Wargear and go to combat choosing to attach the grafted wargear to an opponents creature. If I move the wargear to another creature is the creature the wargear was attached sacrificed?
In general, the sacrifice will succeed only if Grafted Wargear and the permanent it was unattached from are controlled by the same player.
When Grafted Wargear becomes unattached from a permanent, the player who controlled Grafted Wargear at that time is the one who's asked to sacrifice that permanent (C.R. 608.2c, 113.8). However, if that player doesn't control that permanent, they can't sacrifice it this way so that there is no effect (C.R. 701.17a, 101.3).
In general, if you control Grafted Wargear and attach Grafted Wargear—
from a creature you control to some other creature, Grafted Wargear's triggered ability will trigger, since it was unattached from a permanent, so that you must sacrifice the creature it was unattached from this way when the ability resolves (C.R. 701.3d).
from a creature you don't control to some other creature, Grafted Wargear's triggered ability will trigger, since it was unattached from a permanent, but when it resolves, if you don't control the creature it was unattached from this way, you can't sacrifice the creature so nothing happens (C.R. 701.3d, 701.17a, 101.3).
Yeah, thats what i was thinking as well, i was thinking there would be an issue with not controlling it and i know i cant sac something i dont control. Thank you
