Some 1 drop creatures to apply early pressure would be good. I suggest Swiftspear and Zurgo. Lots of 3 drops, could lower the curve just a bit. Just so you don't get overwhelmed by aggressive decks. With aggro lists its all about maintaining a stable board. Midrange/control making sure your stuff sticks and they end up on the back foot. These are just some observations of mine inclined to help.
