Yeah it does look a nit faster. My recommendations are
simple but they're totally up to you depending on how you want to play:
1) add
drana's emissary so that you can gain life every turn (this will help trigger your
serene steward and
cliffhaven vampire more often).
2) Definitely add the
retreat to emeria enchantment so that you can also get more allies per turn. This way when you're sacrificing your allies for various card effects you're getting rid of the tokens instead of your vital creatures that you need for effect triggers.
3) Also if you're going to use the
lantern scout then definitely add more
kor bladewhirl. This way your creatures always hit first, you get the life gain and your troops will live a bit longer.
These are just some observations you might want to consider.
