It's strongly centered around Gemini with BLS and Chaos Sorcerer as support. Draw power is a bit of an issue. Not too large that it cripples plays, but my opening hand decides the game for me. Other than that, it's a bit slow starting off. Once I can get momentum on it, combo's show up right and left; but leading up to that is difficult.
Any suggestions on trimming some of the fat on this deck in exchange for more conducive cards? Any and all ideas are appreciated; and would really be helpful

- Gen

No Reinforcement of the Army? With a deck of 4 WARRIORS? D:

I'd put in a Dragon's Mirror or 2 over Polymerizaton's -2.

2 Red Lotus, No Herulcean Power. +3 Featherizer (good draw power and deck thin.)

Pot of Duality

I'd remove all (or if you want keep 1) Future Samurai, and put in Evocator the Chevalier. 1500 is not going to give you the same respect as 1900 unless you're effect instantly good.

1 Justi-Break over Gemini Trap Hole

Why do people play Birthright over Call of the Haunted? It's like saying lets play Mirror Force, but instead lets make it more fun by playing Radiant Mirror Force or instead of Monster Reborn lets play Miraculous Rebirth. Either way, if you're not playing monsters like Phoenix Gearfried or Dark Storm Dragon, I doubt you need this.

Don't play the Chaos Brothers...
