Mystletainn at 3. Dux and Mystletainn + Phalanx in Grave=OTK
You might want to consider adding Tempest to the deck after Tachyon Galaxy. Just makes the OTK happen more oftenly.
I also don't really like Legionaire and Aklys. They are not that good.
My suggestions are
- 1 Dark Bribe (not in this kind of decks)
+2 Garuda the Wind Spirit ( Otk with him and Dux + Phalanx Grave)
That will make the deck 40 and really explosive.
If you consider making these changes, adjust your extra deck as well
