An interesting Drytron deck using cards from Lightning Overdrive. The deck focuses on turning off hand traps by using Vendread Battlelord, and then setting up a board to synchro into Hot Red Dragon Archfiend King Calamity during your opponent's turn, locking them out of all card effects. Then if your opponent sets cards, nuke their board with Bethor (5 pops). It's a gg if you successfully summon King Calamity, and can be done with a 2-card hand of only Alpha/Zeta.
The Alpha/Zeta combos are shown off in this video, along with some other cool ones: https://www.youtube.com/watch?v=sVtRJAKwfOw
If you choose the route that allows for follow-up, there is no flexibility in the extra deck at all unfortunately.
There are lots of other crazy things you can do with this deck post-LIOV and also post-DAMA; this is just one of them. Let me know if you want to see more!
