This is the third reincarnation of my Final Countdown deck. I have made a major change in the monster line-up that has made a world of difference.

Winged Kuriboh x3
Spirit Reaper x1
Fire Fox x3
Swarm of Scarabs x1
Des Lacooda x3
Morphing Jar x1
UFO Turtle x3

Final Countdown x3
Upstart Goblin x2
Magical Mallet x1
Lightning Vortex x2
Swords of the Revealing Light x1
Nightmare's Steelcage x2
Messenger of Peace x3
Level Limit Area-B x1
Scapegoat x1
The Dark Door x1

Waboku x3

The upgrade of a Mask of Darkness, Sangan and Unhappy Maiden to UFO Turtle and Fire Fox really helped the deck. R/F and I will do the same

If you like to be janky you can run three fox fire and three gyroid with three The Dark Door for an attack lock of sorts.
