After tonights FNM, made the following adjustments:
Syphon Sliver is being replaced in the main w/ Virulent Sliver. For 1 drop, this adds another pair of cards that can be hit T1, also another card that can sidestep Blood Moon if it is on the board. Deck went 1-3, w/ 1 loss due to me arriving late and missing the first round.
Rounds went Loss, 2-1L, 2-1W, 2-0L.
First match went well, with the highlight of the deck catching at 3 health, and going to 1 w/ a thoughsieze. Missed a CoCo draw entirely (4 land 2 spells), but managed to hold back boggles to end the game after 25 minutes swinging for 91 in the air w/ indestructable & lifelink.
2nd match was against a G/W Eldrazi brew, which managed to beat me in the race game 1, but was not able to fire in game 2. Virulent Sliver was boarded in after game 1, but did not appear until game 3, which was won by a 5 sliver swing, opponent had 2 poison counters, and 2/5ths of the slivers were virulent. (10 poison by itself)
3rd match was decided by 2 clutch board wipes against my slivers, both times coming 1-2 turns to lethal. Unfortunate, but well played, as all but 1 of the games were close.
Also considering moving Sidewinder Sliver to the sideboard, as well as removing 1 each of Predatory Sliver & Sinew Sliver. This to allow room for Aether Vials and possibly additional Collected Companys. Once my Mana Leaks arrive, i can test them to see if keeping the blue control in the deck is worthwhile as well.
