We have a strong following for 1.5 around here and there are tournaments held just about every Saturday at the local game store. The local metagame seems to be filled up by Blue-based Control decks and Suicide Black decks. I'm trying to hit on something that will be either fast enough to get inside Blue-control's defenses and kill them before they have a chance, or controlling enough to slow down suicide while still having a late game against blue. I pretty much need a deck that will come in swinging against these decks while not turning over and dying against the random scruc decks that the local little kiddies like to play.
Now, I'm more a T1 player myself, so bare with me here, but here are my basic ideasin no particular order)

A Stacker-esque type deck with some early acceleration, big artifact beatings and burn spells for controlling Suicide.
A speedy but consistent sligh deck, this is especially nice since Sligh is a non-factor in the local metagame (I'm thinking LG sligh may be the best option if going sligh).

An even faster, though more volitile, Stompy or Slompy style deck.

A bridge/pit style deck to shut down both Blue and Suicide's major damage dealers (morphling and negator respectively).

A UB Control deck with Shadowmages, Hippys and Phids to out card advantage the opponent.

Of course, I'm sure the BD-ers can come up with better options than me. Especially those of you who are familiar with the T1.5 monster. By all means, tell me how to surprise the locals with a deck they never expected.
