I'm really surprised people so frequently cut a library. I'd sooner cut the 4th Bob than the first Library. The card is a sensei's top on crack.
In other news here's a small report of two weekly events.
R1 Miracles: G1 He has Forces and STP for my hand, and I topdeck manlands while he topdecks counters. G2 I board into D&T and get under him. 2-0
R2 Jund: I keep a loose 7 and am able to kill his goyfs and keep him off of 1BB for long enough to win. G2 I'm down to 1 life and into forced chump mode with Dryad arbor, then I topdeck a Knight and she ends up winning me the game. 2-0
R3 Eldrazi: G1 my opponent has 2 quick smashers. G2 I Jund him out. G3 Goes super long (~T20) and I don't ever have 4 mana sources at the same time. The second tutored up Displacer killed me. 1-2
R4 Eldrazi: I don't remember these games. I tempo him out without much trouble. 2-0
R1 Cycle.dec: My opponent isn't playing cards that interact well with me. I luck into T2/3 Marit Llages both games. 2-0
R2 BUG Elves: This is the weird brew that recently top8ed the thing. I'm not aware of the decklist and it hurts me. G1 he does his thing, G2 he stumbles on mana, G3 I flood out. 1-2
R3 Miracles: G1 I play a quick chalice, play around Counterbalance, and generally don't let him interact. G2 my T1 Thalia gets there. 2-0
R4 Esper Stoneblade: G1 my opponent had discard and counters, but no threat and not enough mana, so eventually something resolves and I win without knowing what the opponent is on. G2 My opponent Resolves a TNN and a Jace and I can't find a 3rd land. G3 goes super long. I loam for marginal value (1 thicket, 1 wasteland) while my opponent does basically nothing. Eventually I start the 2x Stirring Wildwood beats. With <20 card left in my deck I find a Knight and Bob into Zeniths. My opponent isn't able to find enough relevant cards and concedes to the overwhelming advantage. 2-1
