OK, actually, they probably weren't the ones photographing their own villainous machinations, but you get the picture
Youve got to toss two cards unless one of them is a creature, which makes this perfect in creature-heavy builds
However, Charizard VSTAR's regular attack, Explosive Fire, deals extra damage if Charizard VSTAR has damage on it
Side Note: the reason why I chose to only run 2 Swallow's Slashes instead of 3 was because a) I'd found that 45 was a good deck size, with an 85% chance of opening with a play that would lead into the minimum of Fraulein or Samuraisaga, so to add a third copy would mean either dropping Trinities or bumping up to 50 b) Swallow's Slash requires a Shiranui monster in your deck to be banished, so while running multiple copies would be good, they would typically lose their usefulness as the duel would go on due to not always having Shiranuis in the deck to be able to resolve it
That still doesnt change the fact that Ive seen this card do some disgusting things both when playing with it and against it
