Comments:After the tournament I made some small changes, I replaced both Barbed Foliages,

because I always changed them with something from the sideboard. I added a 

llanowar elf and a river boa instead.

Comments: To solve the problems I had with Birds of Paradise and Mana Elves 

I added 3 Pendrell Mists instead of the Ophidians that I never used.

I also added mana leak, the first stronghold card I use on tournament

level.

Comments: I know it's Slemr's Deck, but I changed it just a little bit,

 by adding a Rainbow Efreet instead of a 4th Steel Golem. I also used 4

 Force Spikes and 3 Mana Leaks to counter early in the game, especially 

against agressive decks, like sligh or white Empyrial. Sideboard: Included 

Wasteland to deal with Volrath's Stronghold or Recurring Death decks, or 

with other Stalking Stones or Quicksand. Note after the tourney: Don't lay

 a disk, with a Rainbow Efreet in play when you have only 4 Islands and a

 Quicksand, or you'll lose. Believe me, I know it, cos I did it. It did cost

 me the 2nd place at the tournament.

Comments: This is deck is quick and usually uses bolts, lions etc ... to bring 

opponent down, then play tutor for twister. Play twister, bolt, incinerate,

 blast ... kill :). I'm thinking about changing Ehrnam Djinn's 

for Sylvan Library and a Chain Lightning. Also Null Rod in the sideboard would be useful 

against Mirror Universe. Comments are welcome.
