MTG: Izzet v Golgari Duel Deck

This weekend I've played Magic the Gathering a few more times with my son and enjoyed it. He needed a bit of cajoling into playing the first game and he said he would only play if we could play with the Izzit and Golgari duel deck I had bought a few months ago in Manchester, specifically he wanted to play the Izzet deck. It was a good game and he used the Izzit Boilerworks card to good effect, using the ability of the card to create the mana he needed to summon his creatures and instants. Eventually, he beat me with his Shrewd Hatchling creature. I played with the Golgari deck and just didn't make effective use of the graveyard, which is the way to play the deck. I did have a good card I wanted to play but through a couple of bad choices didn't get the chance to play it.
On Sunday, my son actually came to me and asked for a game, which was nice. So we played and I won. He did hit me with a good Instant spell called Prophetic Bolt. We were both waiting for the right type of Land card to use the creature cards we had. I was lucky because I was able to summon a creature first even though it was a low power one. I just wore him down slowly.
I'm happy how we're both enjoying playing the game and how we're picking up the intricacies of the rules. We also spent some time sorting out a couple of decks from the Gatecrasher Fat Pack I bought. I can't wait to try out my first built deck.
