+2 cards and -3 threat in exchange for a minion which will likely die from a hammer throw? Easily Thor's best card. I will always play this unless there's no threat on the scheme for some reason. However there are some villains like Rhino who has less minions in their deck so watch out for that.

Also found it to be a resource agains Ultron and made matters worse in the Wrecking Crew as I went thru the encounter deck of that particlar villain. I'm sure it's great "normally" — knotilla · 1
Actually, according to RRG v16, the threat would still be removed even if no minion was found: "If a card ability discards a specified number of cards from the encounter deck or until a card with specific criteria is discarded, discard cards from the encounter deck until the discard condition is met or the encounter deck is empty. If the encounter deck is emptied this way, that card ability is considered to be fulfilled. Do not continue the discard effect with the newly shuffled encounter deck." — Leo_the_wookiee · 3
I disagree. The rule is to prevent infinite discarding, but it doesn't follow from it that the cost of "put that minion into play engaged with you" is considered paid if the deck runs out. — Alatreon · 98
