I mean, he already lost when he failed to FTK
Gimmick Puppet, true to their name, has 0 grind game or comeback plan. Much less against god damn Mitsurugi lol, and the other guy is playing Pure Mitsu, which is like, not even the most bullshit version of Mitsu lol.
The manga really make it looks extra flashy but if we look at what Kuroda did on Hyakuman's turn.
Negate 1 card, Hyakumen dodge by discard 1 card, Cattle Scream which is already a dead card in hand, so it's neg 0.
Tribute Murakumo to add another Habakiri to hand (do nothing)
Futsu reborn a Habakiri, which again did nothing as Hyakuman doesn't look to direct attack
Murakumo come back and board wipe <- real interrupt
Purrification to stop Rouge Doll <- 2nd interrupt (add another mitsu, useless)
Finally Impulse the fiendish knight and destroy it <- 3rd interrupt. And now Kuroda is ran out of thing to do outside of crossout call something
TLDR: Kuroda only has 3 interrupts, with one of it being a board wipe. If Hyakuman's deck was built better, something like 1 Cattle instead of 2, don't run god damn Pathfinder (Seriously, what the heck lol), and load in more power spell, forbidden droplet/triple tact talent etc etc etc. He could have easily pushed through 3 interrupts.
