I only see three flaws with this plan.
You can't TU a chimera.
The most dragons you can have in your hand is 7, and then one slot for the chimera. The highest attack dragons are
Ruby = 15
Arctic = 13
Sky = 13
Silurian = 13
Light = 12
Jade = 12
Amethyst = 12
Total = 90
90 < 100
Your opponent is obviously going to sit there watching you build up quanta when you have no defense.
