Yami Yugi - DarkMagician / Slifer (LOTD:LE)

This is the deck of Yami Yugi (ATEM) for legacy of the duelist link evolution.

The main strategy is to control the board with DarkMagician's engine/tech and when you find Slifer, you can use Number:42 Galaxy Tomahawk to tribute summon it.

This is the closest we can get to craft a realistic and fair to play deck, without the newest support for Divine-Beasts.

The only worth mentioning (generic) card that is able to search for monsters without attack points such as "XXXX" or "????" (like Slifer and Ra) is the "Deep Diver".

You might get better cards for your extra deck if you try to optimize it more (Linkuriboh and Salamangreat Almiraj aren't that good for example) !

Some cards that are level 7 and out of archetype were added to make rank 7 monsters easier to summon. 

"The True Name" can be combined with "Soul Servant" or "Deep Diver" to special summon Slifer from the deck, but at the end of the turn Slifer returns to the graveyard.

The reason I chose this archetype to summon Slifer is that there are plenty of reborns from grave (Eternal Soul), good draw power (Soul Servant), good control of the board (Dark Magical Circle) and the best anti-trap control (Dark Magic Attack). This archetype gives such a nice package to make even the garbage Slifer monster, kind of usable. Not only that, but this deck can learn new players how to make combos and that they have to look-ahead of some turns, while it gives them the chance to feel like the most known protagonist of the whole franchise of Yugioh.
