@Soren841, don't feel bad about it. I only went to the midnight release and I had enough in my 1 card pool to build two separate decks. MY decks were balanced mana wise and even though I built them larger than most peoples they needed it since they were tri-color with minimum support each. The decks ran well but at the worst times, like clockwork, I always got mana flooded or strangely mana drought at the wrong time. My overall record was 1/3/1, but most of the people I played against were young people and I was able to teach them some new stuff since it was also their first time going to a pre-release. Overall it was a good night though. I actually posted both of my decks under the deck review if anyone wants to see them.
I second a lot of what was said here, it's good advice. Sealed is challenging in several ways.
First, you are stuck with what you have in your pool. That's ok, because so is everyone else, so like mana
flood or screw, it all evens out eventually, and you can put that part on luck and save yourself from the feelsbad.
Second, it is a different way to play. Since you can't pick and choose your cards, removal and evasive creatures mean much more since you're at luck's mercy. Games go longer, and cards you wouldn't look at twice in constructed are viable in limited. In limited, people love a repeatable effect that draws 1 card for 4 or 5 mana.
When you get a pool that doesn't have obvious bombs, ample removal concentrated in 1 or 2 colors, or tons of evasive, value creatures that just scream out: "Play me in RB, dummy!" - the most fun thing is to build 2 just-ok decks (maybe some card/color overlap). In sealed and draft, all your cards are sideboard eligible, so if your mediocre rw aggro creature deck gets beat game 1, sideboard into your 2nd deck that's mediocre ub control/removal. Really messes with your opponent
I think it's great you tried an event like this, but it's too bad your pool wasn't stellar. Limited's mana curve and card valuation takes some getting used to - I still have trouble findingt the less-obvious synergies, but they are there. The hardest part for me was getting used to making due and finding janky value. I hope you try more, these events are a great chance to do pick up edh games in between rounds or find new edh players for a regular playgroup.
PS - I tried all day to hit an
induced amnesia, exiling my hand, followed by getting tishana down and destroying the
amnesia enchantment to bring all those exiled cards back to me, pumping tishana. Totally win-more, but sealed is the best excuse for silly jank like that. I could have lost every game and been happy if I hit that just once.
