Does nobody see how awesome brute strength is? His fist check is a bloody BYY. That is a pretty good card.
It's a nice ability, as the double-yellow is great for an attribute test (the blue much less so). I'm always a little hesitant about double-surge checks, but with the double-yellows, it might be reliable enough to count on it. If so, the fact you can exhaust to perform an interact at no action cost is a nice bonus.
That said, it is strictly an interact/attribute test card, so its usefulness in combat will be minimal (unless there are upgrades like the survival suit that require attribute tests to trigger bonuses). Not sure any interact card is worth 3xp, and based on group composition (Loku, Mak), there may be teammates that can have similar effects at a better price point.
Will have to think about this more...
He can't be stunned, he can't bleed, he can't be weakened... He can get a free interact, and possibly 3 movement points (2 for 2 strain, plus 1 from the one class card), meaning he can move 3 spaces, open a door, and shoot twice - with a possible additional red die on his attack, possibly GGRR if he's focused as well. And we still need to see what new weapons there are, and what his mission reward is...
