Yu-Gi-Oh! Warrior Group Deck

First of all, the Warrior Group deck is presumed to rely on high offense (I don't know if D HORE counts as a Warrior Group) or swarming (Rokumo is a good example) to gain an advantage. However, a warrior group's high offense is no match for a dragon, and a swarm beatdown is better if Black Feather thinks so. If you really want to group Rokugan, then this is the way to do it:

Rokugan Masters 2: An important card for Rokugan to play in a group fight.

Rokumo Gun Left 2: Direct attack looks good.

RokumuZong Firegate 2: Again, a good card.

Rokubuzo Ninjou 2: Not sure what to say about this, but it's good in a real battle.

Rokubuzu Iran 2: obscene flow

Rokubuzu Shadow Warrior 3: Rokubuzu's only coordinated card.

True Rokubuzu Ruihui 2 Rokubuzu's Herald 2: All good cards, Rokubuzu's monsters are never in short supply, so after popping your opponent's card, hit them with a second hide.

Rokubuzu's Goryuyo 2: I can't say if it's a good card or not, you can put it in or not.

Purple Flame of Elder China Rim 2: It's a good card.

True Rokubujo - Bamboo Blade 2: Works with Rui Hui.

True Six Musume - Yin Ghost 2: Chain.

True Six Musume - Edge 2

True Six Musume - Kiyama 2

Great General Purple Flame 2: Combined with True Purple Flame, the opponent only has to talk with monsters.

True Six Musume Ziyan 2: Combined with Great General.

Rokumugo Unity 2

Book of Rokumugo 2: Use this to save when one's monster attack is a trap activated by the opponent (e.g., if the attack is an encounter with a Magic Cylinder or something like that).

Rokumo no Rei 1: Same as Rokumo no Shu.

Purple Inferno no Kasagi 1: I don't really know what this can be said to be useful for.

Portal of the Sixth 3: It's so stuck.

RokumuZongPushSen! 2: For emergencies.

The Living Sword Art of the Blades 2: If you use up the summoned monster before the end phase, it seems to not deduct blood.

God's Speed Gear 1: Not much use for a Rokumugo that's entirely a Speed Summon + Group Bash, this card.

Central Breakthrough 2: Useful in actual combat.

Intimate-Backwater Formation 1: Try not to use this card until you can finish off your opponent with it or your own blood is at 500 or so.

Purple Flame's Ruse 2: Seems good.

Six Feet of Agar Hooker 2: Protects against swarming tactics.

Rokubuin 1: A true field spell for Rokubuzou, can add this card without Ziyan's Kasagi.

Based on your request you can add these three cards: one randomly placed by the three gods, one by Future Fusion, and the Creator God of Light - Hel Akti. Slate seems like it needs to be a seven-god artifact. Upstairs says it doesn't have Light Creation, but it actually does.
