Unpopular Opinion: Let people post their fringe/high bracket 4 posts. Make one card suggestion then move on with your day.
Yes, degenerateCEDH exists. Who cares? I'm not advising we give bracket 4 advice. This sub is mostly dead outside of like 3 cards per set, people asking about a commander and moving the discussion to discord, or people in the "wrong" sub. Those people are almost always people who ARE genuinely trying to win the most efficient way possible but they just don't understand the gap between brackets 4 and 5.
We have to be the most unwelcoming community ever. It's like if an amateur birdwatcher was expected to memorize a bird catalogue before they were allowed to ask questions. Responses are always "fringe", "not cedh", "wrong sub", or "look up a decklist". Why not just suggest one or two cards and why they're good? Why not just get them closer to bracket 5, even if it's just one increment?
Cedh is about playing to win, they're almost always here because they're TRYING to play to win. They want a few tips, why can't we just give them the tips? I think it's incredibly lame and unwelcoming. I usually try to give tips when people make these posts, or if they ask about a commander that's genuinely bad I let them down easy. It's not hard. Just assume they're you before you ever got into cedh, and help them get a little closer.
EDIT: Just to clarify, I am not advocating for us making bracket 4 suggestions. Lot of comments seem to think this is condoning bracket 4 for this subreddit, it is not.
