Runming Dreamer, Lilith, and Pandy, a Teddy would be a great pick up as all 3 can benefit from his presence (although, Pandy and Dreamer have better synergies with Teddy)
Dreamer is tough right now as many of the models he likes a lot are not in plastic yet. Insidious Madness, Stitched Together, and the Twins (Lelu and Lilthu) are only in metal right now as far as I know. They can be tough to find.
For Lilith, get a Nephilim box. Those Youngs and the Mature are scary, scary beasts in melee.
