Why the supernovas? Youre basically waiting on the cards to let the combo go off, if you play the supernova's then an enemy black hole/enemy pests can drain the mana before you use it. And if you keep them in hand, they take up space you need for the combo.
I would replace the supernovas with quantum towers.
Also, the blessings make the rubys stronger, but it isnt like you cant win without them.
Instead of 4 blessings, how about for example 2 Ruby Dragons, and 2 electrum hourglasses?
Also 3 Liquids may be a bit much too. Consider switching to 2, because you only need 1 in the entire game.
Instead take another twin universe, or maybe a chimera.
Currently to twin universe it twice, you need 2 out of 3 twin universes in the entire deck. This happens on average after drawing 2/3e of the deck.
With a bad draw you could have 1 or even none at that time.
So if you want to twin universe it twice, you will need 4-6 copies in the deck.
If you want the combo to go of reliably, then you will need as many cards as possible of the main part of the combo.
Currently you need 1 dragon (average on the 10th card, but in the worst case it could be that you need to draw 27 cards)
2* blessing (on average you have them on the 15th card with 4 blessings)
1*liquid shaddow (average on 10th card)
2*twin universe(on average on the 20th card)
1*sky blitz (on average on the 15th card)
This is a 7 card combo. Most likely one or more elements will be missing until at least the 20th - 25th card drawn.
This is assuming you have all the mana as well by then, unless facing earthquakes/pests this is probably the case.
Now how can this be improved?
1) Instead of just ruby dragons, consider using other creatures as well. For example, a steam engine that is powered for 4 turns will have a higher
attack power than a dragon. An upgraded steam engine has 15 health as well, which is good as it needs to survive those turns powering up.
On the plus side, it does damage as well, and may win the game even without any other card. On the down side, it doesnt fly.
Others to consider are Lava Golems/Destroyers and Forest Spirits. These can get pretty huge too.
2) You might consider upgraded chaos power (entropy), instead of bless, it gives a random bonus instead of a fixed one.
If you want the combo to go off reliably though, i would not use bless/chaos power at all.
3) Liquid shadow is primary there to give EM, if the combo goes off. The same can be done with say Miracle/heal or miracle/holy light.
It splits the cards needed to pull the combo off into a 2 card combo, and the main attack combo.
Thus drop Liquid Shadow.
4) Twin universe you will want many of, assuming you can pay the mana for all of them. But if the target creature isnt improved with bless/chaos power,
instead of a twin universe, you could also do another copy of the basic creature. This doesnt work with steam engines/lava golems/forest spirits etc.
5) Finally the sky blitz is needed to double the attack power of the flying creatures.
So now you need say 1 primary creature (ruby dragon or a grown other creature)
With say 4 ruby dragons, 2 forest spectre out of 30 cards, you will on average have 1 in your starting 7 cards.
No blessing/Chaos power/Liquid shadow. Instead 1 heal + 1 miracle. Include more if you want to have EM more =) (8 out of 30 cards used so far)
14 quanum towers for the mana (22 out of 30 cards used so far)
2* sky blitz (24 out of 30 used so far) (on average drawn on the 15th card)
2* Electrum hourglass (to speed up draws, 26 out of 30 used so far)
and finally 4 twin universes.
Now you need a 2 15 strength creatures + 2 twin universe + sky blitz to do say 15*4*2=120 dmg.
Note that with only 1 creature it is 90 dmg, which might be enough considering the powering up forest spectres.
Instead of a 7 card combo, it is now a 4 card combo,
much more likely to happen.
Instead of the 2 forest spectres, one more twin universe + 1 ruby dragon can also be used.
Finally you might consider adding defenses, as asking to survive for 13-15 turns against say a grabix deck that can kill you in 5-7 turns is a bit much...
