1) You should be more careful. Whenever you play a card, you should think to yourself: "Why?".
If there is not much of a reason to play it, just don't.

2) Once when I was new to competitive YGO and my friend kicked my ass, I complained I had bad luck and didn't draw the right cards when I needed them. (Even though I had consistent deck). He then said that those are my decisions that determine how the duel will look later in the game. Your decisions build the entire duel.

3) You should save cards that can do different combos at the same time. More options, more probability you will be able to escape hard situations or make it hard to your opponent.

We had like 4-5 turns when both of us didn't attack. I just passed and you kept summoning more and more GBs.
I had Neos Wrath in my hand ever since the first turn and I had 4 ways to use it:
1) Dump a Neos with Prisma.
2) Neos Alius' eff.
3) Summon a Neos via Necroshade's eff. (Which I dumped early so I won't happen to draw him).
4) Use Hero mask.

I didn't do it because I had 2 Warnings on the field and, that would be a waste and It was smarter to make you waste cards and summon monsters and nuke the field only when necessary.

When I finally got a beater that could destroy your GBs, there was not much you could do.

In the few last turns your hand was empty and there was not much you could do, while I had enough ways to Fusion, Nuke the field or bring 2500 beaters, as well as Special Summoning with Monster Reborn...

In the second duel [b]you did the same mistake.[/b]
[b]
In one turn You wasted your entire hand + Limiter [/b]and tried to attack me while I had 5 Spell/Traps on the field.
If I had a way (And I had more then one) to survive that, you would end up wasting your strongest cards and being left with 0 cards in your hand. Since I had many traps and still had cards in my hand, that was kinda suiciding.
When I Mirror forced you, It was already 99% decided who was going to win here.

It's DH's turn. MP1.
