So I'm going to try and recreate one of the tournament decks that managed to hit top 8 in one of the regionals last year, it's a blue/green infinite combo deck based on Intruder Alarm. So far the basic deck construction looks like this:
Intruder Alarm x4
Llanowar Elves x4
Birds of Paradise x4
Imperious Perfect x4
Sprout Swarm x4
Essence Warden x4
Coiling Oracle x4
Should be fun, I'm curious to see how it would stand up in multiplayer, with all that burn and removal floating around. Oh, there's a bit of counterspell in the deck to to prevent such nastiness ^_^
