Speaking of Fighting Fury Belt, doesn't that Tool Card also put a lot of EXs out of Night March's OHKO range? Let's say that, atm, the Night March deck has 4 Lampents, 2 Joltiks, and 2 Phantumps in the Discard with a Muscle Band Joltik/Pumpkaboo on the field ready to attack a 170 HP EX. That's 180 damage already, but Fighting Fury Belt makes it so that you have to sacrifice 2 more Night Marchers or even 3 more depending on circumstances in order to OHKO a normal EX with Fighting Fury Belt without exposing weaknesses. That diffuses a lot of Night March's offensive potential and leaves it more vulnerable, even if the deck can just recycle resources with Puzzle of Time.
