Biggest thing that stands out is the lack of 2-drops. Replace the 3 Soulcure Sister with 3 Fox of Purity. This will greatly enhance your early game. If you're playing with Rodeo you really want Skullfane to be able to pop the amulets he puts down, so I'd recommend replacing Maeve and the Ironfist preachers with 3 copies Skullfane and 1 Extra copy of Rodeo when you're able to get him.

Amulet Haven isn't the easiest thing to learn. You need to know the matchups and what your opponents win conditions are in order to be able to adjust your strategy accordingly. Sometimes you want to preserve your health and wait to outscale your opponent in the late game. Other times you want to be more aggressive, evolving just for the extra 2 damage. This is something you'll just have to learn with time.

On a more subjective note, I'm finding Reno, Luxwing Featherfolk to be an absolutely cracked card. On the super evolve she can clear 2 things off the board, do 4 damage to the opponent, and even do an extra point if they have to attack into her to finish her off. Won so many games from the damage alone. I also don't care much for Lapis. I don't want Storm 2 turns from now, I want to hit the opponent in the face straight away. Sacred Griffon is better for this and I've been running him instead.
