Venom Burn recently, came out as a Ranked Ticket R. You can stockpile counters on those 0 atk monsters to do some actually heavy burn damage. it takes about 12 counters to OTK with it but you have 3 chances and the field puts a counter on all faceups at the end of every turn.
Weirdly Boxer's have mixed well with them, the R4nk floats, the R3 can stockpile, Veil stockpiles but eh.
I have no problem activating it. You have Zombie in your GY but is that a 0 DEF Zombie? Many Zombie type don't match that 0 DEF requirement. Gozuki, Pyramid Turtle, Nine Tailed Fox, Goblin Zombie are not 0 DEF.
Anyway, this is a card that Shiranui will never use. More like a piece of useless card.
The OCG text, if anyone's curious:
エンドフェイズ時、このカードをエクストラデッキに戻し、自分の墓地の「スターダスト・ドラゴン」1体を選択して特殊召喚する。
Endofeizu-ji, kono kādo o ekusutoradekki ni modoshi, jibun no bochi no `sutādasuto doragon' 1 karada o sentakushi te tokushu shōkan suru.
During the End Phase, return this card to the Extra Deck, then select 1 "Stardust Dragon" in your Graveyard, and Special Summon it.
I wonder what would be the point of such card existing later, though.
Most cards that retrieve stuff from the Graveyard don't look at ATK to begin with anyway. And those that do, aren't really used by anyone.
