Merfolk > UB Fairies

I haven’t played much MtG recently, but fired up Merfolk tonight.  I thought UB Fairies would be a good matchup but it went to 3 games.

I had one game where I had a Mutavault and Aether Vial in my draw, which I kept.  I went on to not draw a single blue source of mana the whole game.

Another game I didn’t see a single land until I drew 4 cards, and that hand was 3 lands, 1 Vapor Snag.  I kept that hand.

So I did win one of those games, which was it?
