Some suggestion...
If you want to get Destiny End Dragoon fast, you can either abuse Stratos with Warrior Returning Alive and 2 E-Emergency Call+1 Reinforcement of the Army, to get the necessary component fast, and use 3 of each Plasma and Dogma, along with 2 Destiny Draw, 1 Allure, and 2 Trade-in for more consistency and getting rid of bad hand. And use 3 Polymerization instead of Fusion Gate, since you prefer the material to be in the grave.
Dasher and Defender don't have any good contribution for this deck. Swap it for Plaguespreader Zombie (that goes well with Malicious) and 1 Prisma instead.
hope it help.
