Well I learnt a lot from these matches and tought, why not share it with the community.
1st vs Mytho sealed:http://battledexgame.com/game.php?game_id=16767
I felt like a supernoob after my defeat here. Besides not getting to submit some turns, I'm sure I could defend my cp advantage. I won't commit the same mistake again.
2nd vs jojo constructed $50 tourny:http://battledexgame.com/game.php?game_id=16803
Someone told in chat jojo tought I would baserush as I didn't get my resource on first turn. While I didn't base my strategy on getting my oponent tricked, I tought on first turn "oh, maybe he'll think I'll baserush, good for me".
3rd vs Mytho constructed $50 tourny:http://battledexgame.com/game.php?game_id=16808
Nothing much to say here. I knew he'd have superior cards so I didn't care to try to take the middle at the beggining. I think I needed to keep focused on the sides and I realized it too late.
