PlainsI am not sure the build was right, and in the sideboard I had more Sure Strikes, more 2-drops, and more Maniacal Rages, but this is what I went with. I was not expecting Direct Current to be very useful - seriously, it's just a 3-mana, sorcery-speed
Shock - but in one game it mattered by clearing away a Hammer Dropper. Otherwise the deck felt strong and I had good draws. The one game I lost, my opponent attacked me for 5 with Whisper Agent & Dimir Spybug when I had 7 life left + a 3/3 Swiftblade Vindicator. I decided not to block, since it's possible he might have Dazzling Lights and my swingback was lethal given my pump spells ... then he had two more Whisper Agents. Ultimately though I think I played well, which really helped. One particular play I'm proud of is this:
Me: 3/3 Wojek Bodyguard, 2/2 Sunhome Stalwart
Him: 0/3 wall, 2/3 Boros Challenger (stolen with Connive//Concoct)
It's turn 4, and I'm holding two Sure Strike and Hammer Dropper. He has four mana open. Me on autopilot would undoubtedly have attacked, thinking that if opponent blocks and has a trick I have Sure Strike to counter his trick anyway. Then I realized that he has the mana to pump Boros Challenger (thanks to Gateway Plaza). Me on semi-autopilot would still have attacked, using a Sure Strike to kill his Boros Challenger, since that's what aggressive decks do right - use combat tricks to force through damage. But me playing carefully realized that I could just play Hammer Dropper and not attack. After all he didn't add to his board last turn, while I'm adding a 5/2 mentor. He ends up even further behind on tempo and the Sure Strikes would still be around to force through damage the turn after. Sure enough, after I decided not to attack opponent tanked for a bit and sacrificed the wall to itself, and the game ended shortly afterwards with an overwhelming board state on my side.
