Why do I always lose round 1?

I've just qualified for the French nationals by playing in the Regnional championships of Paris. (We are still old style, we might a NQ like everyone else starting next year)

It has been an observation for a while, and I never took the time to analyse it, so I'm doing it right now : Why the hell do I always lose round 1?

Let's search on my total rating page and search for numbers :

So in those last 14 tournaments, I lost round one 10 times, drew 1 time, and won 3 times (but lost round 2 once).
I made 1 top 8, three 9th-10th place at 7-1-1 and qualified for the French nationals.




I got some really nice good story to tell. But I really think this can't be by chance.


First one Good Story : 
My first extended PTQ this season, I've just seen an interesting jund deck which made top 8 on MTGO and I switch a little before the tournament for Jund instead of whatever I was planning to play. I make some changes making the deck more explosive, but, in fact, worse.


Round 1 I got to play a 5c control deck. I win the first one, loose the second one on a double Cruel Ultimatum and we are playing game 3. He's a 3. I thoughsized him and discarded him a baneslayer last turn, he drew land and played it. I play and attack with a demi god to force him to sacrifice his UW manland.
On my board, 2 man lands and other lands, in my hand 2 demi gods of revenge.


My oponent draws, plays preordain, one top, one bottom, plays spreading sea, draw, play spreading sea, draw, play spreading see, draw and pass the turn.
I draw blank.
He draw, play cruel ultimatum, get back a kitchen finks and I got myself 0 cards in hands.


Of course he won this game.




As much as this story seems to be bad luck (or good luck for my opponent) I learned one things : My deck could have been better and if it had been, I wouldn't have lost this game since he would have been long dead before beeing able to make 4 top decks.


This is one of the reason I lose round 1, I am not always playing a strong enough deck. Like playing Bant lately in a fairly well prepared fea field. (and playing fea with to few preparation)


The second reason is probably concentration.
I've always have been someone who has a lot of difficulties to concentrate, so this could make sense. Not sure I'm doing more mistakes round 1 though.

The third one, for limited event is probably not knowing my deck enough. When I play in Limited it takes me some time to understand my deck fully and use most of it's ressources.

I've been trying to strenghten those points, but I really still only lose round 1. So there should be other reason lying around.
Couldn't find them yet, do anybody have an idea?
