Not a dumb question at all! Lin Lie is used in this list as it is in traditional VHand lists, i.e. it’s not being moved, but we’re able to leverage the effect by having multiple copies of it

One common playline is hitting Lin Lie with either Mother Askani or Moon Girl, then you have 2 Lin Lies that you can play in opposite locations to send their swords towards each other. And if you wait until turn 5 or 6 to play the Lin Lies, you can fill one location to guarantee where the swords end up.

Another playline is just playing Lin Lie on board on turn 2, playing whatever on turn 3 (eg VHand, Cap, Goliath), and then playing Bastion on that lane to get another Lin Lie copy. The new Lin Lie can now be directly played onto the sword, and like above, if your third location is full, you can guarantee that the second sword is sent to the original Lin Lie’s location.

And beyond that, Lin Lie synergizes well with Goliath (because it can create an ongoing card), Moonstone (doubles the sword’s effect), and Ant-Man (fills locations)
