damn this is cool, maybe you could put
Leyline of Anticipation in the deck since 2
emergence zone might be kinda gambly to get with the combo.
Lazotep Plating i think i would put in a counter spell or a
murder or something instead since you have so many small creatures, so it wont be good for your opponent to
murder a 1/1 anyway. but i like the idea with
liliana's contract and arcane adaptations but i think your deck wants to do too many things tho, i would trem it down to only be the liliana and adaption combo, so maybe having the small creatures have some card advantage on them to find the combo, or they give you more bodies like
Lazotep Reaver or give you life to survive. i might be wrong tho
