Whenever an opponent taps an artifact for mana, gain control of that artifact until the end of your next turn.
The artifact remains tapped when you gain control of it.
In a multiplayer game, if a player leaves the game, all cards that player owns leave as well. If that player controls any nabbed treasures, the effect giving that player control of those artifacts ends.
If you control multiple Treasure Nabbers, their effects all expire at the same time. You won’t keep an artifact for any longer.
An artifact is “tapped for mana” when a player activates a mana ability of an artifact that includes (the tap symbol). Notably, tapping an artifact to pay for a spell with the improvise keyword is not tapping that artifact for mana.
