This is very easy to include as long as you have a useful weapon upgrade to get. In aggression alone, you could search a Hand Cannon for a Follow Through deck or have this be like a second copy of Jarnbjorn in your deck. There are also many heroes with powerful hero-specific weapons like Gamora with her sword, any of Rocket's toys, or 2 of Black Panther's Wakanda Forever upgrades, so this is a nice tool for those decks. These player side schemes have done an awesome job of helping you make decks built around a few specific cards be much more consistent!
Also, the flavor text is a John Wick quote right?
