Focus on Licia, once she gets out and she's above a 10/10 she's a huge threat.
Find more bombs (3-4cmc) and
Protect Licia and protect yourself, if they can't hit her they'll hit you
Don't limit yourself to Vampires
You could go a more enchantment based route
Less lifegain more make Licia disgusting
No shroud, you need to be able to attach effects to her
