It seems the cost of this card is very low.
This card steals a power 3 card of the opponent, but the minimal cost of a card is 4 resources.
Asumming a theft of only 4 resources, is a benefit of 8 resources. Adding 3 power points of Sweers, the total benefit is 11. But the cost of the card is 10. Too cheap to be the worst case.
Asumming a theft of 5 resources card, or 6 resources card, is more evident this problem.
