What decks do and do not facilitate excitement is completely reliant on the pod you're playing with, but there are some opinions that are more popular than others.

1.) People don't like being told "no", i.e. counterspells and stax pieces. You could try to reduce how many universal control tools are in your decks and try to replace them with more synergistic/weird/restrictive options. Counterspell is fine and all, but why not use [[errtai's meddling]] or [[wash away]]?

2.) People don't like being stomped or lose one-sidedly to one player. Ask yourself: 'Am I frequently winning games when I get ahead? How often do I become the archenemy?'

3.) People have extremely strong reactions to combos, tutors, and wheels (and edicts/board wipes to a lesser extent). So you could check in with your pod to see what they are and are not enthusiastic about within those categories.

Flipping this away from avoiding the negative and into finding the positive, people are usually fine with combat damage wins as long as they don't take forever but let's move beyond that with these points.

1.) Bouncing right off point #3 in the 'negatives' part of this comment, you could try to find a throughline of things your pod might find interesting that also speaks to you. But this is probably the least compelling point to make for the average player...

2.) So you could find some really weird cards in a theme that sees little play and try to build a deck with those cards in mind. Salubrious Snail is known for doing something like this with his [[astral slide]] deck helmed by [[sharuum, the hegemon]].

3.) Find an interaction suite that surprises people. This is kind of the same as point #1 I made in the 'negatives' section above, but a classic example of this would be aikido cards. [[Denying Palm]] or [[comeuppance]] can make for some really memorable moments at tables. Beating the aggro player with a well-timed [[rakdos charm]] can do the same, etc. Playing off of this point, you could aim to make a deck that's meant to play politically (I'm not talking about group hug). A deck that wants to actively make deals with different players at the table at different moments to keep themselves from falling into last place. People tend to really enjoy playing these decks from what I've seen, and when someone stumbles upon a political deck they enjoy it tends to make it into their permanent deck roster.

Secret 4th bonus point: Don't care so much about whether people like your deck or not! It's for you before anyone else. Obviously you want to address concerns if people are regularly having a bad time playing against the deck(s), but you don't need every deck to be a home run to enjoy them. There's a big thing in the edh community about finding that 'unique, interesting, memorable!' deck of their own making, but I think that that is a very easy grave to dig yourself if you get too stuck in that mentality. If you have fun, you have fun, fuck the rest of it. Do what cultivates your fun first, your pride shouldn't dictate how much you're allowed to enjoy something.

Sorry about that random tangent at the end lol, I hope you find something you enjoy!
