I don't know why this came to mind, but I had to make a DM for it when I saw the art. ^^;

Coach Goblin
Group: Fiend/Effect
Type: Earth
Level:4
Icon: Deckmaster
Atk: 1200
Def: 1500

Every time a Normal monster is normal summoned, flip summoned, or special summoned, place one "Knockout Counter" on this card. Remove 3 "Knockout Counters" to increase the ATK of a normal monster by 300. Remove 5 "Knockout Counters" to destroy one monster on the field, regardless of position. If this Deckmaster is summoned to the field with 10 "Knockout Counters", you may remove one counter from this card each turn. When 10 "Knockout Counters" are removed consecutively in this way, you automatically win the game.

KO! :)

Edit: Just to clarify, Normal monsters are any that don't have an effect. I didn't know that until I read up on Ancient Sanctuary, lol, but you guys probably knew already.

i like it its like monster egg but better. i like how the monsters have to be normal good DM DD.

can you say final destiny? there is no way you can keep a mosnter like that alive for ten turns. this DM needs some kinda powering up, maybe something along the lines of..
