Well I sorted out the really bad ideas, and here's 62 decks that have sprung up over the months. They all indicate the deck size, but I gave up on trying to cram colors or cubes into the names. I'm really bad at organization though. I have no idea how to sort all this stuff sensibly.
Most are average strength and fun to play against AI random decks, but there are a few that accidentally ended up being real monsters:
Warriors Rush 2015Five of the finest steppe warriors. If you're lucky, you can deal 20 damage in four turns: 1. (anything), 2.
Battle Brawler, 3.
Arashin Foremost, 4.
Chief of the Edge. Even if you don't get this combo, it's still a frighteningly fast deck.
ChromaThis deck routinely destroys anything that takes more than 5 turns to start (although it's still weak in the very beginning). Gather up a land of each color, then throw around major 5-color spells like
Bringer of the Black Dawn,
Maelstrom Archangel and
Genju of the Realm. Also contains the entire Honden cycle from Kamigawa (
Honden of Seeing Winds etc.), just for fun.
Draw Your GoblinUnblockable goblins that summon more goblins for free. Plus draw power. What's not to like?
Mardu MayhemAnkle Shanker is just plain evil. But even without it, there are lots of really cheap Mardu cards whose only drawback is having two or three colors.
Mirror StompAnother 3-color deck that becomes overwhelming very quickly thanks to strong 3 CMC creatures, enters-the-battlefield abilities and clones.
But my finest hour is the deck I call simply
Argh! No, it's definitely not powerful, but it's the most counterintuitive deck ever! You win by making your opponent gain life, summon creatures and cast spells. Even the humble
Grollub finally finds a use when your
Kavu Predator eats up the lifegain! It also gives whole new use for cards like
Collapsing Borders,
Malignus,
Grove of the Burnwillows, and anything that gives life to the opponent. You also get cards to manage your opponent's lifegain, like
Quietus Spike and
Pulse of the Forge. To add insult to injury,
Dragonlair Spider,
Taurean Mauler and
Heartwood Storyteller are used to give you benefits no matter what the opponent does. Damned if you do, damned if you don't!
Other fun surprises include
Trees Are Useful, where Treefolk are actually good for something, and
Rot Farming, where you load up your graveyard with creatures but
don't animate them.
