After making a lot of changes, converging into the new proto-archetype for Blue Devotion seen in the net (see changes further down, and see EssTea's list, Mono-Blue Devotion Is Back!), I took it to Game Day because my other ready alternative was Boss Sligh and I thought it would perform badly in the meta... it turned out I lost nearly all games (see next) and the only Boss Sligh attending ranked penultimate, beating me effortlessly...
Changes:
3 Rounds: 1 draw, 2 losses; 8th Overall (yep, just 8 players for Game Day, that's what you get when you schedule Game Day in the same day as Valentine and Carnival...)
Round 1: Classical boring impersonal Abzan Midrange netdeck
This is one of the best players in my LGS, and always plays pure netdeck versions; he is a very archetypal Spike player and spontaneous lecturer... He sported a classical Abzan Midrange deck, including Tasigur, the Golden Fang as a novelty from the last 2 weeks...
Game 1: win
He was mana-screwed and would not play anything but a "cat" (Rakshasa Deathdealer), which I single bell striked to his dismay, for several turns. I started beating with a Triton Shorestalker from turn 1, he Hero's Downfalled my turn 2 Frost Walker and I cast a turn 3 Thassa, God of the Sea, which was critical, as without her upkeep sustained scry I would have drawn islands for 7 turns in a row!... This game lasted nearly 30 minutes... After Drown in Sorrowing my elemental tokens, I cast another Master of Waves with a Bident of Thassa (which granted me like 7-8 cards in the game, by the way) and a Thassa turned on, and he conceded.
Game 2: loss
I managed to neuter with Singing Bell Strike an early cat, exile a Courser of Kruphix while manifesting a land (which died with his own Drown in Sorrow), and most especially... steal his Siege Rhino with Hypnotic Siren!, he clearly was not expecting that, as I usually don't save her for late game control magic. Then I made 2 epic misplays: Cloning his Sorin, Solemn Visitor with my Clever Impersonator instead of Negateing Sorin and cloning my own Master of Waves. He went ultimate with Sorin and outraced me with his cats and coursers... This game drew considerable gathering as everyone had already finished round 1 and they were to see if the rookie would beat UltraSpike or not. On countless ocasions I disappointed the other players with my choices and plays but then I was mindful of asking them to tell me what I should have done throughout the game...
Round 2: Slightly original Abzan midrange, with a Sultai-ish tweak to include some Delve cards...
The 2 games were quite similar and fast. He Thoughtseized and Despised me in the first turns and it took me a while to draw answers to his cats, Rhino, Tasigur, and most especially Sorin... he even had Hooting Mandrills in his deck but did not draw them. He would kill my creatures with Hero's Downfall and Murderous Cut in game 1 and then also with Bile Blight after SB...
Round 3: RDW hybrid between Boss Sligh and Rabble Red, with no FRF altogether
This a friendly player, to whom, ironically, I made suggestions on how to improve his RDW a while ago, as it was very slow. I sent him many primers and lists from the net, suggesting to scrap any spell with CMC > 2 save for Stoke the Flames, and any creature with CMC > 1 save maybe the Goblin Rabblemaster. He executed all suggestions and totally beat me, though any other player just crushed him... Rock-paper-scissors MTG, I guess...
Game 1: he outraced me. I was unable to stabilize. He had an Akroan Crusader, a Foundry Street Denizen, and a Goblin Rabblemaster out by turn 3, and many tokens from the Crusader's Heroic and the Rabblemaster's ability. I traded some of my wheenies and exiled the Rabblemaster but was within range of two Lightning Strike...
Game 2: I carefully sideboarded 2x Monastery Siege, 1 extra Polymorphist's Jest, 2x Aetherspouts, 3x Negate. Despite casting a turn 3 Monastery Siege which saved my creatures from direct damage, and despite trading my wheenies for his, I was unable to stop all his wheenies and a convoked 6-CMC Stoke the Flames... I think this deck is just incapable of resisting a RDW... Turn 2 Hammerhand on Akroan Crusader would prevent in both games a Frost Walker from killing his pumped Crusader or Rabblemaster...
Overall
A disappointing performance, though this was Game Day and nearly every player wears a Spike mask and plays Top 8 netdecks, whereas I was sporting a pet monoblue deck which is fun to play (stealing a Siege Rhino or a Tasigur with Hypnotic Siren or exiling them to have the opponent manifest a land is great), but statistically should be no match against current top8 netdecks... Too bad I misplayed so badly game 2 against would-be winner Abzan Midrange as it would have made me place well above...
The rest of the players were: Azorius Heroic (netdeck, Spike player), BW wheenies with Atreos and Whip of Erebos (original deck, Johnny player, he's been playing this deck for ages as he despises netdecks), UB Control (netdeck, Spike player), and my favorite and an original deck at that: Grixis control with FRF dragons, Chandra, Ashiok, and Ugin. This deck had crushed everyone the day before in FNM, sometimes without even SB, and I wrote about it when writing on my testing of the latest iteration of this deck in EssTea page, Mono-Blue Devotion Is Back!.
Overall results were: 1. classic Abzan Midrange; 2. UB Control (these two players are the usual winners in all FNMs); 3. BW Wheenies original; 4. Abzan Midrange with delve spells; 5. Azorius Heroic; 6. Grixis control with dragons; 7. RDW; 8. me.
