Several new builds in DE

A solid WP boom for Aztec
This build takes use of 2 war hut travois shipment. 2 war hut worth 500 wood itself; however it will take huge time for your villagers to open crates and build them. And don't forget that this shipment gives 20% extra HP to war huts (2000-2400), giving you a very stable base defense with only one shipment. Without war huts you can also defend with endless minutemen and an undead warchief, but you will lose huge amount of XP if your priests dance for minutemen constantly.
Send 3 villagers first. Age up fast with 15 villagers. Send Calmecac right before you click age up, and it will arrive right after commercial age.
When Calmecac arrives, dance for new priests with 2 priests and 10+ villagers, leaving 5 on food for constant TC training. You don't need 3 priests or fencing school here: if you send 2 shipments for priest boom, your later shipments are delayed.
The next 2 shipments can be rather 5 villagers into 2 war huts, or 2 war huts into 5 villagers. It depends on whether you'll be pushed or raided early. For example if you're facing German, just send war huts first and uhlan raiding is nothing, and you don't even need units to defend it.
So at around 6:00, you have 10 priests, 3+5 villagers sent, 2 buffed war huts, and can age up fast. Your eco is solid, your shipments are endless, and your base is unbreakable. You can send 600 coin 700 wood and arrive age 3 before 9:00 with 2 noble huts, switching into fortress play smoothly, or go industrial directly. Colonial play is also available (though not recommended). Imo this is the most flexible build for Aztec in current patch: you can deal with almost anything with this.

Haud mantlet 2.0 build
1.0 build uses 800 resources into 7 Huron mantlet. Though 800 resources is a great shipment, it delays your following shipments too. In 2.0 build we age up with wise woman instead of messenger, gather 350 coin during transition, and send mantlet directly. You can always have 2 shipments before 6:00 (generally 7 mantlet and 4 Kanya), and can even be used on non-TP maps. Besides, this build can hardly be scouted: your opponent can't decide whether you're doing a mantlet timing, or a semiFF.
The build order is rather simple: just do standard start, send 3 villagers. On land maps build TP, on water maps build dock and train 3-4 vills. Gather 350 coin during transition (with fishing boats too), and send 7 mantlet asap. Train tomahawk or Aenna archer (depends), send unit shipments, push.
With mantlet you have enough siege to break the defense: Agra Fort, blockhouse, watchtower, and even TC. You don't need to overcommit with your infantry: they're just used to protect the mantlet.

Brainless Hausa FF
RE Ottoman FF: 3v, 700g, 700w, 8 jan, 2 cannon, 1000g, 5 mameluke
DE Hausa FF: 2v, 700g, 5 akan, 5 lifidi, (4 lifidi), 1000 inf, 5 sennar, 15 dervish
It's even not needed to describe the build order in detail. Differences are within the age up options: with Songhai (camp+300 coin) you can do a smooth FF, and can afford some market techs during traisition; with Hausa (camp+300 wood) you can't afford these investments, but you gain more resources and can switch into boom with influences. For fortress age, Morocco (mosque and 600 XP) gives one extra shipment which is quite nice, but Akan (6 Akans) may help you hold a timing push too, and you can use influence for more akan from native embassy.
You need a TP during transition for 250 influence shipment. With a recent balance change you may not exchange 200 wood right now, so chopping 200 wood and age up with 300 coin may be a better choice. You can exchange for more resources as you saved a cow.
If you age up with 700 coin into fortress and send a cow, you may even do a FI. What do Hausa have in age IV? I'm not sure, but at least you have auto-upgraded area-damage musketeers.
