I only played the Japanese and hard bot match so that pretty much I known for this game, play most of times in supremacy mode, hope anyone would found some use from this notebook.

basic
gather order (the saber icon)would sending to all military units in you hand to location, it would call anyone so this order pretty useful for those units which spared around in maps, however they won't react to enemy who attack so maybe use the attack move would solve this problem.

food or gold(like mill) building need about per three of them to maximum your economy, so total are six of them, did build tower and army to protect them for enemy harm.

early stage you need food more(800 foods) later you need gold more, the final stage you need wood more than anything cause wood won't grow back after you cut it down.

more player meaning you team would gain much more from the green cards, cause they give a huge buff or units as all teammates in team.

shift key could select ion all units in area, Ctrl key could deselection the units which you in control.

word
first thing first, you need to build two deck, one let you fight in ground the other are sea battle.

Green card are those really useful card due it give all teammates the buff or units, still some like give tiny monster units for you team is kind of useless still the decision is on you hand.

for beginner there are two way are defense or assault, defense meaning more economy focus and build more tower to push out you territory that keeping you ability to recover from enemy attack, the assault are sending much an much army size as fast as possible, which are really risk but reward heavy if you using you attack troops well.

The card choice
I won't give suggestion which single of the card name to pick with, the name list are too long so I only say in simple way like using gold or food or army or buff that kind of thing....

• Early: you would use the worker card if food run low, use the house card if wood run low, gold won't run short in early and since there natural recourse are plenty in early so food and gold building (like mill) are not need that urgent.
  
• Mid: you rise a level age, now you have two way as below, if you bot teammates at rise do extent you defense building to those weak spot, start strike down enemy weak spot, there are not true answer which card are much useful than other cause it simple too many option.
  
• Later: building six economy building to maximum resource are the key to win later stage battle, after that you needing more wood card due there little wood in maps now, or replenish your troop double from barrack and battle cars are the option open for you.

Master the Japanese

first thing first, as Japan your shrine building would provide resource and they would attract animal, don't building shrine too close to your bot ally since they worker would try to hunt animal and stuck there, since they can't kill the animal who tame by you shrine, this is a huge bug that developer never fix anyway.

Level building choice

• To shogu shrine: provide the income resource, ASAP cause this thing are powerful thought out the whole match
  
• The shogunate: don't rush out this building in stage 2 cause this building need to stage 3 to produce the general.
  
• Great Buddha :give all location from enemy units which are the beast skill to turn the battle upside down.
  
• Golden pavilion: give the buff you choice and provide other buff by spend resource on them.
  
• Torii gates: exp are not that important, maybe you could got some shipment much faster if you really want for tactics concern

Consulate choice

• Portuguese: sea battle use
  
• Dutch: give you a bank which generate gold which is huge
  
• Spanish:more shipment only choice this when you known what to do with the shipment.
  
• Japanese: more training block for army (up to 10 units)

IDK, I just use the Dutch in most matches, would switch to Japanese for army upgrade

little tips

• with two monk at start which meaning you explore whole maps twice as fast.
  
  
• there are two dojo which you could got it from shipment cards when reach age 3, which you must to rush out the dojo as fast as possible for the free army spawn.
  
  
• there are tons of buff or building that gain trickle of your choice resource

defense first, you need to known the bot would always win you from economy to army size, the developer give more resource to bot so they always win, if you want to win the opponent you need intelligent.

things to do

1. building one or two tower push out the territory so you could have times to react first wave of enemy troops, keeping your troop alive and fight around your tower central, if you need then call all your worker fight death with enemy troops, since you still would lose if worker left in hand so let you worker went to battle are one of the option.
   
   
2. protect your teammates as you could, by building out the tower you teammate would react to enemy in sight, if your teammate got wrecked terrible maybe send some resource to them, it won't help it they lose town central so act quick.
   
   
3. second base, you need to building out barrack out and town central out for second base which grant your much points to fight and defense, after that you could hunt down enemy building as you got space and resource spared in hand.

I would list out the basic way to start the match, as I say before the choice is in your hand.

age 1

• rush out market and the upgrade.
  
  
• build or shipment two house.
  
  
• build a tower to extent you territory
  
  
• 800 food to next age

age 2

• build barrack and produce or card drop troops for you
  
  
• build more tower and wall to protect your land.
  
  
• only strike back if enemy invader your or teammates land
  
  
• stack the population as high as you could, no rush just keeping the population so you could keeping build out troop.

age 3

• strike back enemy, you done defense a lot of attack from enemy now is your turn to strike back.
  
  
• spend resource to upgrade troop and buff as you could no rush for them.

age 4
