Its a different type of the standard nova-immo rainbow.
1: I would recommend taking out the Guardian Angel, because it costs too much and the attack is too low.
2: Then I would remove steal, because it costs 4, and that is too high for this type of deck. It also takes away dark from the lycanthrope.
3: I'm not too sure about the fallen druid, but you can keep it if you want. Otherwise swap it for a precognition.
4: Take out Deja Vu. It's not good unupped. Also, swap Acceleration to Momentum. Acceleration won't work well because none you your creatures have high hp.
5: Switch Forest Spirit to Horned Frog. OR Take out Mind Flayer and add Thunderbolt. I personally prefer the second option.
4: Next, add another of immolation, and another Phoenix. This will give the deck more consistency.
5: Lastly, switch the 4 photons to sparks. sparks have higher attack, so they can be used as a burst of damage to finish an opponent off.
6: Now add either a blessing or relective shield. I perfer blessing, so I will add that.
So, after my modifications, it would look like:

As a general rule of thumb, in this type of deck, don't take anything above a cost of 2 or 3.
