I am building a deck of females for a friend of mine who really likes Performance of Sword, and I'm planning on adding Amazons, but which ones? And it's to be build using the new April 1st banned list.

[3] Performance of Sword
[1] DDWL
[2] Manju
[6]

[1] Snatch Steal
[1] Swords of Revealing Light
[1] Premature Burial
[3] Commencement Dance
[3] Smashing Ground
[2] Nobleman of Crossout
[1] Graceful Charity
[2] Reinforcement of the Army
[14]

[1] Call of the Haunted
[1] Torrential Tribute
[1] Mirror Force
[1] Ceasefire (another card he likes)
[4]

Amazoness Paladin is a prett sweet one, and maybe few Swordswomans, Tigers could be considered a female...

Gotta agree here with DangAzn here for the simple reason that if you make a female Warrior-based deck, Amazoness is the way to go. That plus Performance of Sword is a good ritual to break out ---- IF you have protection built into the deck. As far as female Warriors, here's a handy starting base idea:

at least 2 of each:
*Amazoness Blowpiper ---- excellent payoff here
*Amazon Archer
*Amazoness Paladin
*Amazoness Spellcaster
*The Unfriendly Amazon ---- if you have recovery for the monsters or a handy Scapegoat stashed in there, then you're in good shape with her.
*Princess of Tsurugi ---- not Amazoness, but check her effect.
*Lady Ninja Yae ---- find some Wind-based females and you're good.
*Invader of the Throne ---- if she's not destroyed in battle and you have Book of Moon, her effect is nasty.

That's just what I've got off the top of my head.
