I played RB Instigator at my local shop last night.
Just a simple report as I know GoboLord likes to have both the good and the bad for completeness.

Rd1: 2-0 vs UW Countertop Miracles.
G1: He stalled me with Ensnaring Bridge, but I had a swarm and a Matron for Tuktuk.
I didn't see many of his cards but my guess was Miracles.
Sideboarding OUT: 3x Gempalm, 2x Tarfire, 1x Warren Weirding, 1x Stingscourger;
IN: 3x Therapy, 2x Earwig, 1x Tuktuk, 1x Mox
G2: The game ended with all four Ringleaders swinging in for the win. I'd prowled in Earwig earlier taking both copies of Entreat and a Jace, and my hand was full of goblins in case of Terminus.
Rd2: 0-2 vs Death & Taxes
G1: mull to 5. Get owned.
G2: mull to 5. Get owned.
SB: can't remember exactly but I took out 2x Piledrivers.
Rd3: 1-2 vs Pox (mono-black LD Nether Void version)
G1: He gains complete control and I find myself with no land, no creatures, and no hand. I scoop to save time.
SB: my sideboard is terrible for this matchup. I took out most removal, bringing in 1x Tuktuk, 2x Earwig, 1x Mox, 3x Therapy.
G2: Multiple Vials plus Warren Instigator, 2x Chieftain, and a massive storm of goblins result in me swinging for 18 even with Engineered Plague out.
G3: his early Cursed Scrolls with Engineered Plague, and Pithing Needles on Vial and Krenko, prevent me from establishing any board presence.
Finished: 1-2 in rounds, 3-4 in games.
SGC hasn't hit the board once in 15 games, including practice games. That means either it's not needed, or I should be Matroning for it instead of something else.
The D&T round was vs my friend. We played about 8 games on the day, of which I won just one. The other 7 were nightmare blowouts in his favor. He was able to consistently deal with my early threats, establish a superior board (usually with equipment), put Revoker on my Vial or Gempalm, and Port my lands. This matchup was a complete nightmare. Pyrokinesis and additional, cheap artifact destruction were sorely missed. I'd appreciate any tips.
