Leveticus is more than likely to bring a ranged game against Euri.
That being the case, you should consider that if you get deployment. Choose a side that might be able to give you cover or concealment.
Second, place Ice Pillars just outside of 1 inch from the opponents models to form a wall (in base to base with each other). Make them waste AP on taking down the wall of Ice Pillars.
Conversely, use Ice Pillars to give yourself cover.
With the exception of Ashes and Dust, most of Amalgam isn't known for their exceptional MV, so drop Ice Pillars to deal damage to Levi's crew and himself. Bringing a Cyclops to give models staggered will also help tremendously.
Use the Damned (if you have them) to scheme and waif hunt.
