Guys, this deck is super fun to play, and it's cheap as dirt (and easy to make cheaper, if you just want to play with it)
Originally inspired by this deck, our game plan is to mill the opponent as fast as possible. We're throwing in a number of easy ways to keep our hands full while nuking their library, and it works surprisingly well.
A lot of the cards we're playing give us additional draw (benefiting Psychic Corrosion and Jace's Erasure, though erasure isn't as good in a multiplayer game), and every spell is blue (playing to Drowned Secrets's strengths). We can also play around with other draw effects, such as Induced Amnesia (which combos well with Blink of an Eye, because we can bounce it back to hand).
Thoughts:
The deck can consistently mill an opponent's 60-card deck by turn 7-8, and can do it at turn 6 if lucky. It has a fair amount of interaction, but it probably would get trounced in any serious game. Let me know if you can think of a way to improve it!
Interestingly, Radical Idea is one of the best cards in this deck - something that I did not really expect. However, it plays well with BOTH types of mill enchantments, can be played from the graveyard, and can be double-played, leading to some amazing sudden victories.
It's a real shame that the rules interactions associated with it don't let us play around with Day's Undoing on our turn, which is an effective library nuke in conjunction with Psychic Corrosion, were the triggers to work like that. However, combined with Mission Briefing, it's got a real possibility to shine (too bad I'm too cheap to buy more Mission Briefings :P). Even without that interaction, it's worth adding to get a good-sized hand to interact with other cards (like Induced Amnesia) and "mill" the opponent for 7 more cards.
