I call it "Lob" for the tactic of "lobbing" cards at my opponent to set up the kill. Shien's Spy, Magic Box and Creature Swap lob Griggle, Ameba and Rat at my opponent, allowing me to benefit from the effects and set up a viable attack target for Lily. It's not a OTK, but it can hit pretty quick, and pretty hard. So far it is 7-1 in playtesting against three different decks. It is a work in progress. Suggestions are welcome. I thank Dr. Card for the idea that got this started.

You know, this deck could easily be a OTK deck: Inferno Reckless Summon played after a Giant Rat's effect. Bam, three Lily's, 9900 damage during the battle phase. That makes for a big dent in someone's life points, lol.

I'd minus two Shien's for two of them, personnally, and it would still leave the Creature Swaps and the Mystic Box for your 'lob' tactics.

I'm no meister deck builder, but that's my two sense ;).

EDIT: It would not be a chain, it would be played after, lol.

Thanks. most definitely something to consider.

That could work if my opponent has a monster on the field with 1500+ ATK and I know they only have one copy in their deck. Suicide the Rat into their monster, SS the Lily, flip IRS, bring out the other two, make sure you have 6000 LP to give up and then go for it. You would do some damage with the first attack, depending upon their monster, then two clear attacks from the other two Lily for 6800. It could work!!
