Looking at this card in a vacuum, we may say it feels like it lacks a bit of punch for the cost. In practice though, it does the job.
This card needs to be evaluated in the context of the psionic trait because that's a constraint of the card anyway.
From an economic standpoint, it allows us to use Team-Building Exercise, Martial Prowess, and all the other discounts like Helicarrier. It can also be paid by Power of the Mind.
Even if we gauge its value at full price, the most important for damage is mostly to look at the ceilings it can cross, more than pure ER / damage ratio.
As of the end of the mutant cycle, we had around 300 non-nemesis minion cards with 4 or less hit points. This card can one shot about 70% of minions for 3ER, without any requirement.
Then if you add Psimitar, which works almost like a dedicated spreadable Honed Technique for this card - it reaches 90%. And you can cumulate both Honed technique and Psimitar for an awesome 2 costed, 8 splittable damage with ranged, which puts swinging web kick to shame. Don't sleep on this.
