The biggest deal for me is that it's only 28 cards, which makes it unplayable.
11 pendulums are too unstable. With that, it's constantly swaying between quanta you can and cannot play. take 4 out for fire pillars and 2 out for grav pillars.
Throw in an extra weapon, either Fahrenheit or Pulverizer and it might be better
I approve of this, and instead of those, I suggest Titan.
I also suggest the highly abusable Immolation, cheap sacrifice of a simple Phoenix for an extra 7
and 1
.
This is also a moment to think about the Control that you can get from these two.
Gravity has the powerful and the most high HP creatures ever to appear on the face of elements. In effect, Flying Titan was 70 HP, and is now nerfed to 50 HP. From merely that, we can see how grav creatures have a LOT of health.... which opens up the opportunity for "extra life", namely armaggios. Also, chimera = pwnage.
Fire is one of the 3 most obvious elements which can do both Permanent and Creature Control consistently, the other two being Darkness and Earth (Entropy can, but Creature Control is either by chance or situational).
With this in mind, filling your deck with more deflags and rage potions is the way to go.
