Megalith

Note regarding UR's:
● The Main Deck is very cheap aside from staples which are cuttable.
● The Extra Deck contains lot of Stapes too and is Flexible.

Caution: Even though floodgates are run, you need brainpower to play this deck!

The Deck aims to end on Vanity's Ruler or Barrier Statue of the Drought (Only possible if you do not have to Normal Summon a Manju/Senju to combo) and plans to OTK turn 3. Sadly Magician of Black Chaos MAX does not exist in Master Duel, so this can't be used as backup strat in case you have to Normal Summon a Manju/Senju. Instead you end on either:

● Number 41 (against most decks)
● Dweller + Herald of Mirage Lights (slaughters drytron)
● Nephthys, the sacred flame (slaughters Sky Striker and other decks that cannot out a dragoon-like monster)

Plus lots of followup.

Good points about the Deck:
● Extreme Followup and grind (Ritual Spell in the GY gives you insane plus turn 3+)
● Can search Nibiru or Blockdragon if needed
● Can OTK with any Level 4's (Accesscode line)
● Can get High ATK with Phaleg (for unaffected bossmonsters)
● Toolbox Extradeck
● Ends on Floodgates (Yep fun) but can win without them.

Bad Points:
● Dies to skilldrain in most cases.
● Engine alone is over 40, so with HT's and going second cards its 60 cards. Still very consistent but you see non-engine cards less
● Feather duster/LS hurt pretty bad, Portal is an important card.
● Can play around Maxx C only a little bit (Number 41 Turbo - still draw 2 or more.)
● In a best of one you kind of don't know what to make for the endboard. Against drytron you lose if you end on Number 41 for example.
● Appolousa is a scary card for rocks
