Notes & Combos
Intro
Very cheap deck for Legend Anthology. Surprisingly works well and very easy to play.
All the Main Deck Warrior monsters are capable of either summoning itself without Tributes, or summoning other monsters from hand. It is a simple beatdown deck which offers plenty of interaction through its Rank 5 toolkit.
Deck Cost
The only two important UR cards are Constellar Pleiades and N.As.H Knight, which are your main source of interactions. Constellar has a Quick Effect bounce, while N.As.H has a Quick Effect to attach 1 monster to itself (does not target).
Note that N.As.H's effect requires a "Number" Xyz monster in your Extra Deck to work, which is why the Extra Deck has Number 102 and Number 104 (any "Number" Xyz monster can work; these are the cheapest options). I rarely need more than 2 attaches. You can put more "Number" monsters in if you feel you need to.
Aside from these two, you don't need any other SR or UR cards. Raigeki and Monster Reborn are free, Face Card Fusion can be replaced with any cheap staples or Fusion Sage, Obelisk is a meme card I put in because I have it, and Tiras and Gunkan can be replaced with any Rank 5 monster you have or more "Number" Xyz monsters to fuel N.As.H Knight's effect.
How to play
Standard line is to Fusion Summon Idaten, then get Constellar Pleiades and/or N.As.H Knight on the board, or other Rank 5 monsters depending on what you need. Thanks to how easy it is to put your monsters on the board, you are almost guaranteed to at least summon a Rank 5.
Idaten on Special Summon searches any Level 5 Warrior, which usually would be Kaiki if you don't have it in the GY yet. Activate Idaten's effect to discard at least 1 card (usually the Kaiki you searched) to increase its ATK and allow Kaiki to be Special Summoned during opponent's turn to Fusion Summon Shura if needed.
Dismantle your opponent's board using your Rank 5s, swarm the board, and win through beatdown.
