This power is a difficult power to have activate, or even to plan. It is similar to Post-Hypnotic Suggestion (7/PO), except this has a stronger effect (but requires you to attack and lose, giving spoils). It requires that you attack, be defeated, and the defender survived, blocking many common strategies found in winning decks.
Champions who could survive such a situation work well to setup this power, such as Ochimo (95/FR) (since the defeated attacker doesn't have to be psionic), Seveia Shadowmaster (14/PO) (though it gives the opponent spoils), or Minerva (333/4th) (removing spoils).
Being able to use this card after losing battle and just having another psionicist use the power after the defeat is very useful, but still requires losing, and few decks plan to lose.
Don't expect to see this card too often in tournaments, but this would be a very worthy addition to a poison-pill theme deck with just a sprinkling of psionic champions.
