This is the deck I used for Farming and the "beat 100 story characters" medal/crest on Dark Abyss. For lack of a creative name, we'll go with Old McD.

4 Bandit
4 Dragonoid
3 Ethereal Queen
1 Bistair
4 Pillar of Flame
4 Bloody Pudding
4 Carbuncle
1 Selenear
4 Wall of Stone

4 Fly
4 Haste
4 Manna
1 Omnipotent
4 Permission
4 Wind of Hope

When you set up the game, pick Dark Abyss - Set the Magic Goal to 8000TG - Turn Taunts OFF - and make all Lands Level 2. I usually play Sebastian, and make her use her top deck. Not sure what it's called since I can't read Japanese, but it has no Magic Bolts, Evil Blasts, or any other damage spells so all the little support creatures are safe. You'll find she usually won't attack you if you are packing any beefy HP creatures. The E cards are pretty broken, so they help speed things along. Dark Abyss is pretty huge as far as maps go, so just drop Support creatures everywhere you can. Other than the two E creatures, all the creatures cost 40G or less. The two 80ST/80HP creatures are pretty sick when used as support for Bandit. Just make sure she doesn't have any Bucklers in hand. The spells are there to move you around the map and get money. I use Omnipotent to get 5 symbols of each color. Buy symbols, chain and level to win. The game should take about 15 minutes.

I'll have to post some other decks later, but I'm still tweaking them all as I get new cards. When I first started playing this deck I only had 1 Ethereal Queen.
