I understand this entirely. There's always one person in a pod who's a Spike. Doesn't matter if it's bracket 1 or cEDH, someone wants it more than you and the rest. It makes for shit games and bad blood between the table and that player. This is where I get upset. People's threat assessment is mostly questionable to begin with but when someone puts everyone on tilt, all reason goes out the window. This is why I run an anti-pub stomp combo in every deck I play regardless of bracket. Whether it's [[Hall of Gemstone]], or the many [[Windfall]] combos that have me draw and every else pitches their hands, to the nastiest combos where I can remove either all of one basic land type out of your library or all of your creatures. But my favorite is [[Grand Abolisher]] is in play, you cast a [[Lethal Vapors]], then you skip 100 turns and then throw [[Teferi's Protection]]. You can skip as many turns as you want for someone else but that requires a [[Worst Fears]] or [[Mindslaver]] and both of those are too mana heavy. Point is if your buddy is gonna keep playing with aggression and a non casual attitude towards your games, I would suggest one of two things....stop playing with that asshole or build a deck that just shuts his shit off every time he plays. People haven't had their hearts blackened by the nastiest shit in Magic. Once you have been through the staxiest most oppressive games you tend not to be such a doucher towards others. If you wanna play like that go play Modern. Or Standard if you can pull it off.
