Love the videos, Jesse! I believe a unit can pick up a weapon that was used earlier in the turn. On Page 26, the rules state: "Once per turn a unit at rest may pick up an artifact at its location. It may also drop at its location. However, a unit that has engaged in combat this turn cannot drop any artifacts that it is carrying. A unit that has used an artifact’s activated ability this turn cannot drop that artifact." So the Assassin couldn't drop the sword willingly, but if it died, then you could pick it up later. The issue is that the battlemage (I think) needed to move + attack. You wouldn't be able to pick up the sword after moving but before attacking, because "at rest" means "nothing is happening at all." Also, when you fire the projectile from Grapple Shot, you can start from your own site, and your opponent can't chump block the Grapple Shot, since it's not an attack, but a strike. So I'm pretty sure Teleport + Grapple Shot is an inescapable death blow.

Why did you remove your own units? both sword and whirling blades only damage enemy it sais.

What r u playing this on?
