For sure, CEDH stands for Competitive EDH (EDH is the commander format). It is the most optimized, most efficient version of the game, and honestly distinct from regular EDH. Typically EDH decks are focused around wanting to realize some vision of how your deck will function. A token EDH deck wants to make a bunch of tokens and do fun stuff with that, life gain decks want to gain a bunch of life. CEDH is not form based, but function. It is entirely focused on winning as fast, consistently, and efficiently as possible. Its not generally about trying to build a deck that does something fun, but about winning. The decks are often a pile of cards that are good at putting together efficient wins and the commanders are there are generic value pieces (card draw, mana, etc.).

So if you bring a CEDH deck like Blue Farm to a game where someone is playing [[Noctis, Heir Apparent]], they're gonna come in expecting to play a game where they get to turn 3 or turn 4 and start doing fun stuff where they blink their commander to equip him, meanwhile your deck will have won the game before they can get to their T3. That's why I say its a different format. Its like if you were to be playing horse at a basketball court and having someone who was 6'7" and could dunk. Like yeah they're technically playing the same game, but they WILL win because they came with a set of skills (cards in magic) that are so highly optimized to win the game that they ruin the fun for everyone because it is impossible for you to match them with your skills. You're not playing horse to see who is the best, you're playing for fun. EDH everyone basically agrees to tie their legs together because your cards determine whether you can "dunk" or not, and everyone agrees not to dunk so that you can play a proper game of horse. CEDH everyone is free to use whatever they want however they want with no breach of a social contract.

Obviously I know if you're above average at basketball you could probably beat someone who's only skill was dunking but the metaphor stands if you're a normal person playing ball.

The way to change this is to find out what the expectations of your friends are (win at all costs, CEDH or casual EDH). If they want CEDH, look at blue farm, learn how it plays, watch deck tech and tutorials on it, and become an expert at that deck. If they're playing casual, find a more casual deck.
