"Archfiend ~Devil's Unity~" Deck 2013

Playing

Basically, it's a deck that greatly raises the RBI and beats down with Fuumaden and 《Solidarity》.
*Extra proposals are being highly acclaimed.

Strength

His greatest strength is the 1,300 RBI increase with Fuumaden and Solidarity, and if you use this, even at the lower class, you can hit 3,200 RBI with Archfiend Cavalry, 2,800 with trance, and 2,300 with tricks. Also, don't miss the effect of the powerful card [Corruption] unique to the Archfiend Deck. Lava Golem is also a Fiend, so you can use RBI up, so after removing the opponent's monster with Lavago, take it with Corruption and hit it with a high RBI of 4300. Let's make it a trade-in cost when it looks like it's going to rot. Discarding Lavago at the cost of Train will also have the effect of suppressing the opponent's deployment. This is also his slow-footed deck, so if you don't let your opponent's attack slow down, or slow down his attack, it's easy for you to get weak.
Also, after searching for 《Archfiend's Roar》with the trick effect, set it and use the self-destruction effect at the end of the opponent's turn to activate the trick and search again. Or with the effect of Hell Empress, he can be a GY high level monster SS.
To be honest, it's a deck that consumes summoning rights, so I don't really have any ideas for extras.

Weakness

Since it uses GY, 《Dimensional Fissure》, 《Macro Cosmos》, and Burn Decks are pretty painful. Throw in a hurricane or a cyclone with Saichen and be sure to respond.

Customize

If you want to assemble GY at high speed, you can also consider using 《Armageddon Knight》or 《Dark Grepher》. However, since you can't use unity, you can also consider adopting Greedy and Humble Pot because it's a deck that doesn't have 《One Day of Peace》, nouveau riche, or Special Summon in Droso. 《Ultimate Offering》and his easy GY operation, 《Dark Armed Dragon》etc. can also be considered.
