Be Sil'fer and have your dummy char as endu. Endu's Deck is in this order : 2 rag rappies, and then 3 slashes. Then just fill up his deck with random cards.

Sil'fers deck:
1. Chainsword
2. mag
3. Sword Attack
4. Slash
5. Native Guard or just guard(either one should work)
6. Akako's wok (not sure on spelling)

Set Rules : Min roll 6
Max roll 6
Deck shuffle OFF

Level : Unguis Lapis

1. Have endu go first (if sil'fer has first turn skip it)
2. Do not set any monsters and just go forward 3 spaces ( you should be infront of silfer) and end turn.
3. Have Sil'fer equip the chainsword and mag and end turn.
4. Have endu place rappies to the left and to the right of him (so there all in a line.)
5. have a rappy attack with 2 slashes and have sil'fer defend with the defense card.
6. Then on Sil'fer's turn have her equip akiko's wok.
7. have her 1st attack endu with just the wok.
8. Then attack with the Sword attack and slash.

BAM there all dead insta S grade!
