"EX Deck is decoration! Smash it with super high firepower! !" Deck 2018

Playing

By using all possible means to drop Cubic Karma onto his GY, and using the effect of (3), he stubbornly gathers the necessary cards to summon Crimson Nova the Dark Cubic Lord.
《Crimson Nova the Dark Cubic Lord》, 《Cubic Karma》and 《Cubic Wave》can be used for 1 kill.
If 《Crimson Nova the Dark Cubic Lord》's (3) effect is about to kill you, do your best to get two 《Crimson Nova the Dark Cubic Lord》and connect them to 《Superdreadnought Rail Cannon Gustav Max》.

Strength

《Cubic Karma》is easy to drop into GY, so it's easy to get the card you want in your hand.
Not limited to 《Crimson Nova the Dark Cubic Lord》, 《Cubic Karma》and 《Cubic Wave》can demonstrate great firepower.
If all goes well, ATK 5400 with 《Crimson Nova the Dark Cubic Lord》X 《Cubic Karma》,
Furthermore, ATK 10800 with Cubic Wave, ATK 21600 with the second Cubic Wave, and ATK 43200 with the third Cubic Wave! !
There is no limit to how many times Cubic Wave can be activated in one turn, so if you're not careful, you can do it in the first turn.
The wickedness that makes Cyber End Dragon with ATK 16000 look cute.
There is also the danger of collapsing, but the burn damage from the (3) effect of Crimson Nova the Dark Cubic Lord is also very effective.
Even if 《Crimson Nova the Dark Cubic Lord》fails, you can expect Cubic Monarch's burn damage and 《SNo.39 Utopia The Lightning》's high damage.

Weakness

Almost no DEF. If I had to pick one, it would be the (2) effect of 《Solemn Judgment》or 《Unification of the Cubic Lords》.
If your opponent interferes with the summoning of 《Crimson Nova the Dark Cubic Lord》, or if you demonstrate the breakthrough power of Blue-Eyed, you will break into a cold sweat.
You should actively remove her Spells and Traps from your opponent.

Customize

The variety of Cubic monsters is due to his ATK reinforcement by the (2) effect of 《Duza the Meteor Cubic Vessel》and the summoning of 《Crimson Nova the Dark Cubic Lord》.
If you don't expect the former, or if you want a backup strategy in case the latter goes bankrupt, you can restructure one Cubic monster and add Summoner Monk to make it easier to connect to Rank 4 Xyz. Maybe ants.
I have 《Dark Sanctuary》as an insurance in case of some kind of trouble, but instead of this, I can have 3 《Hand Destruction》.
