Death Splinter has some really awesome looking monsters.
I especially love using Cthulhu.
Here's the line up, battle conditions, start/end battle, and replays.
(I usually pick Death Splinter's Owster Rotwell when Water Splinter is available and the even/odd rule allows a few magic monsters which might prove to be a pain but Rotwell's shared Magic Reflect ability is very helpful when faced against multiple enemy Magic monsters.)

(End of Battle - above)
In the end, only the great and almighty Cthulhu remains!
