When The Arsenal came out, he just had keywords for each Landmark that had died that game. That read cleaner and was more understandable and easy to play with since that allowed us to display his keywords in hand.
It turns out, that meant that he could get permanent SpellShield which we hadn't run into since we made that change late in development which we had thought was a quality of life fix. So, we had to make an emergency fix without being able to change the text yet (only time we've ever done that).
And that's why we call him the arsenal! (also, RIP scout as a generatable keyword)
