This is what our record looks like:

The tactics in their exact state that I posted them here have been in use since around the 2025-26 season. I hadn't added the tighter marking and more pressing personal tactics before that. Another huge thing that happened at that time was that I replaced our backup goalie, he was the reason we were down to Pct in the 80s after that early 19-20 .900+ season. So never underestimate the value of a good backup in EHM. There isn't really a good way to check our playoff records that I know of in EHM but I don't remember losing a single game for at least 5 seasons now, probably more. We're at 15 cups in a row and just getting ready to go for the 16th.
Considering this was the first tactic I tried after only ~10 games of playtesting I'm a bit surprised at just how good it is. Sometimes it's better to be lucky than good I guess. It has morphed a bit over the seasons, but it is largely unchanged. The biggest thing to me is that it's consistently remained nearly unbeatable despite a complete change of manpower. There isn't a single player on the team that was on it for our first cup. The personal tactics just get so much value out of your players that it barely matters if your players have 150 PA or 185 PA, you get 100+ points out of either in a good year. We had 5/6 top 6 forwards on 100+ points last season, the only guy who missed it by 9 points was out injured for 7 games, and was projected to hit it had he not been injured. So if you're afraid that bringing two more defensive forwards into your top 6 will limit your scoring, don't be. They score almost as much as your snipers and playmakers do, if not more.
There is one little caveat to mention though, generated players tend to have much lower Natural Fitness than premade players, this leads to your younger players having issues with fatigue towards the later half of the season/playoffs when playing on Overload. This doesn't matter that much since they still perform admirably after getting fatigued, and it helps build their resilience for future seasons. But my quick tip is that when you have 18-21 year old in your top 6 and play on Overload; Make sure that whenever you have a 3+ day rest between games you put their practice schedule on "Resting". The first two days will be spent getting their condition up to 100% again, but the third day will give them a legitimate day of rest at 100%. This helps slow down the rate at which they get fatigued (the little "Rst" box next to their name). I've had 3 young players suffer from this same issue, around their 3rd-4th season they will have gained enough Natural Fitness from being played so hard that the problem will go away. At that point you can stop resting them in the 3 day breaks. Worth noting is that some seasons the scheduling will cause your team to simply not have any 3+ day rests mid-season. There isn't really much you can do about that, just let them get fatigued and harden them for later seasons by playing them through it. I've never seen it have any backlash, and our current player going through this phase scored 90 points his rookie year at 18 and 105 in his sophomore year. So it's not like it kills their production or anything.
