Basically, this is no deck setup, just needs new cards. Try using an Anubis to immortalize a Armagio and in case you haven't got an Anubis yet, try using a Guardian Angel.
Comment by another player:
Immortalizing Armagio is useless, Gravity Pull does function as usual, and Armagio gets destroyed when his HP reach 0.
If other creatured are affected by poison, gravity pull...and then immortalized. Poison, gravity pull, will function till HP reach 0 ->death, even when immortalized.
