Skull Warriors - Discard Yamigitsune Variant

The goal for this deck is to create a variation of Skull Warriors that utilizes the cheap, easily accessible temporary plusses of Skull Warriors, then trade them for direct card disadvantage of the opponent.  Flags that start with lower hand sizes (Dragon Ein, Dragon Zwei) and decks with minimal forms of card advantage can quickly get overwhelmed.  The deck poops out soft and hard advantage like crazy, but if you don't open with the means to do either (all defensive cards, only cards that need to be revived from drop zone), then you have bricked and have to hope you can hold out until you can produce card advantage, although this is rare.

This build plays like most other Skull Warriors builds.  We have removed Shiden and the Ninja Arts engine from the build, as Half-Kill, Minawagakushi, Item Blast, and Mat Flip do far less in this metagame of removal immunity.  Consequently, we are now running more Demon Way cards than ever before.  Sakurafubuki is back to help add pressure and close out games.  With the focus being on forcing discards, nothing is quite as devastating as them trying to use a spell to stop your attacks, then having it nullified, and being forced to discard on top of having their other card wasted.  Again, this deck has an extreme advantage over decks with low card advantage engines, decks that have small starting hand sizes, and combo decks.

There is, of course, the standard play of Goraiko with Yamigitsune to force an additional discard in the main phase.  Benishojo allows you to trade a gauge for a soft advantage that can be converted into a permanent disadvantage for the opponent.  Jugonrensa, Kasumienran, and Benefit all increase life, giving more sustain.  This deck's advantages are many and its weaknesses are essentially only to Penetrate immune, multi-soul, unremoval soul wall decks, Legend World, and bricking.  This deck has many things in place to deal with bricking and many cards can produce soft or hard advantage to unbrick you, but if you cannot keep a board (especially if you get hit with RIP Caliburn), then you can struggle.  Of course, that's in Legend World, where forcing them to discard is usually beneficial for them, so we'll just mark that as a general problem match-up.

Karakurenai is in here, because in a build like this, it's not just plausible, but likely that you will reach a point where they have 2 or fewer cards in hand, and I heard that Infinity Death Crest! was a good card.
