Going First Strategy with directions in chat and follow ups
Going Second OTK with directions in chat(If you go uninterrupted and if you're opponent somehow doesn't lose you have the going first end board as well)
My two other builds have Starliege Seyfert and World Legacy Guardragon, those we're the two major cuts in this deck that made it
"Semi-Budget". Borreload Savage Dragon is in the deck list as well, it's almost 100% needed but its expensive so you could replace a few Rokkets with Rokket Synchron and replace Savage with Hot Red Dragon Archfiend Abyss which can simulate the Negate situation although slightly harder to pull off.
Hopefully both combo replays reflect how strong this deck is with its end boards going first or second.
This obviously isn't my first Rokket list as i'm always adjusting and adapting it to what i feel is good or is needed against the meta. Like all combo heavy decks you can very easily be interrupted by Nibiru or have all you work come to naught by Dark Ruler No More which is sadly something you can't really work around. Knightmare Phoenix is your closest out to Mystic Mine without the Side Deck, hoping you can use enough materials to have the same amount of monsters as the opponent to get the Phoenix effect.
Expect a few more Rokket Deck Lists in the future as Eternity Code brings a new card in Noctovision Dragon which is a great extender for this deck and its only a Common.
