kaibaman can be floodgated or anything else that would stop the effect"

Dumb reason. The blue-eyes that you summon using ancient rules can also get floodgated. Also.. if you summon kaibaman, your opponent knows you're gonna special summon BEWD next, so they'll wait until you do that before they floodgate it. common sense. Duh.
I think the reasoning behind their Floodgate point is Champion's Vigilance making Blue-Eyes slightly more resilient to it. Plus, a 700 DEF Kaibaman's much easier to attack over than a 2500 DEF BEWD.
Simple answer: this card is much more versatile and can be used to Summon Dark Magician too (for decks that run Dark Eradicator Warlock or Sorcerer of Dark Magic)
