I'm not sure what to think of this, it is quite epic though.
Armagio, Supernova, Supernova, Entropy Tower, Entropy Tower, Earth Tower, Apotheosis. Turn 1 Divine Dragon?
Armagio + Momentum + Acceleration/Overdrive + Quintessence is very similar, but more difficult to make.
For Divine Guardian, Gravity Pull would make sense but I don't know if that should be given to an 'Other' card. Maybe it could absorb damage to other creatures you control, and move all poison counters on creatures you control to it each turn? Could be 5|50 or something. Another idea is for it to add to your maximum HP by a small amount each turn.
