Playing the same 4C Enchantress as always.
First match is vs. a little kid playing a really bad black deck. I win 2-0.
Next is vs. Legend. Game 1 we play Draw-Go for about 40 turns before I have 15 
mana and go City of Solitude; counter; Replenish; counter; Replenish; counter; 
Replenish; scoop. Turns out all that time he had nothing but Islands. Oh well.
Games 2-3...Whoa Legend! WTF is this sideboard taking me up the ass? I bring in 
the usual complement of Chokes and Cities of Solitude. He brings in -- 
Ophidians, Wash Outs, and Hibernations. Hibernation KILLS me. My God. Wow is 
that brutal. Me: First turn City. Him: OK. Me: Second turn Choke. Him: OK. Me: 
Sylvan. Him: OK (with like 8 cards in hand). Me: are you crazy? Him: 
Hibernation. He had three 'Phids going at once after I sided out my creature 
control and bounced everything I could cast and then some. Enchantress could 
take the original Legend Blue -- you know, 4 Drain Leak FoW FoF Morphling B2B 
Keg MisD etc. with Blue Blasts and Disks in the board -- any day of the week. 
But facing an army of Ophidians fetching mass untargetable bounce spells? Forget 
about it. I would say 70/30 me game 1, 70/30 him post-board. His bounce 
nullifies all my sideboard hate. How many Thran Lenses must I board in? Other 
bounce hate, anyone?
PS I lose games 2-3.
Round 3 I'm paired vs. Vinny Pau. Game one he's ahead of me the whole way and is 
one turn away from victory...but counters a Worship that would have kept me 
alive, letting me Replenish out approximately 40 percent of my deck. Um, he 
Game two I'm in the driver's seat most of the way, then cast a Worship thinking 
I have a creature when I don't. I ask if I could take it back because I haven't 
done anything else, but he won't let me because it's a tournament. He's probably 
right. So I lose. I think I would have won though.
Game three I run out of time. We play a bunch more games after the tournament 
for fun. The 4 color version is definitely very good against Keeper, especially 
versions like his that don't really disrupt me. I win all the game ones (like 4 
of them). But Aura Fracture makes things tougher post sideboard, especially when 
he also boards in Tormod's Crypt. I lose most of the post SB games. Karmic 
Justice is very good but often Fracture can really keep me down. Any suggestions 
for Fracture hate?
I want to make room for another maindeck Duress but it is just so tight now. 
Basically every card was an MVP at one point or another.
