For Katana, how bout a HD Lethal Formation and Secret Sword card.

Readied Fangs and Claws of the Hundred Demons

[Cast Cost] [Pay 1 gauge & Choose an Impact card from your hand, deck, or drop zone, and put it face down into this card's soul. If you searched your deck, shuffle it] You may cast a 《Hundred Demons》 from the soul by paying its [Cast Cost]. All 《Hundred Demons》 on your field gets power+1000!!

Hundred Demons Sorcery, Overwhelming Possession!!!

[Cast Cost] [Pay 3 Gauge]

"[Counter] When a monster enters your opponent's field, you may destroy one 《Hundred Demons》 monster on your side of the field. If the destroyed 《Hundred Demons》 monster has a greater size then the monster that entered your opponent's field, give it 《Hundred Demons》 and move it to your side of the field!!
 * This card's effect cannot be used on cards with [Omni Lord]."

So the only targets really are any Size 2 - 0s and unless HDs get a Size 4, your opponent's Size 3s are off the table. Plus any Omni Lords as well like Count Dawn and Drum can't be taken to fit in line with Ban.
