At first, this card flew under my radar since I just feel like a higher cost and arguably worse version of Turn the Tide. 4 for 7 damage versus 1 for 3 seems a worse deal when you already need to thwart first. However, not only this become the Swinging Web Kick of some hero, especially Nova who is lack of burst damage when using justice, but also a more reliable way to deal damage. It's certainly not a card for everyone but it's also helps justice hero to deal more damage, especially in a true solo game
If you can mulligan hard for this early game (or use 'Pool aspect Mulligan cards) then it's worth getting into play to buff off of Gamora's consistent draw/play of attack events. Even better if you can then utilize some tricks like Mean Swing or Fusillade to buff her Sword even more. I've been trying to figure out how to rig a more consistent Mjolnir-like pull with the Lock and Load PSS.
This actually works great when paired with Sonic Rifle in rainbow decks like Gamora or Adam Warlock. For single aspect decks, Mean Swing is probably a better alternative if you have a heavy basic attack like She-Hulk or Hulk and want to throw a basic weapon on the hero. Thor is a natural beneficiary of Fusillade because he can pretty much always call Mjolnir to set up Fusillade.
Laser Swords does not need the high-risk Live Dangerously in order to function well. If you simply have multiple 'Pool aspect allies in play, then Laser Swords buffs enough to justify its 3 cost. The longer those allies remain in play the more damage you can do with Hero attacks - which is especially helpful against tougher villains or playing expert cards. Of course the trade-off is acceleration, boost and extra encounter cards...but you control how long and when those allies will be in play. Symbiote Suit is another viable option here.
I can see this being a must-include in every Hulk Aggression deck. I say this because Banner’s ability lets him generate a free science-resource, which gets you halfway to meeting Honed Techniques 2-science resource requirement.
