Need card ideas for my alternate World War I card game, Conscript! Please!

I don't know what kind of mechanic you have in mind. So just some written idea's for now.

Germany:
Speciality is cannon type units.
- Howitzer, a vehicle that needs deployment in 1 turn? Then has a massive destruction on any ground unit. A glass cannon that needs close quarter back-up.
- AA-gun, a structure that does medium damage against air.
- Pantzer! a tank that shows more quality than any other tank. A bonus for each additional Pantzer of +1 damage due to communications.

Soviet Union:
Speciality are rocket type units.
- V2-Launcher, a vehicle that has no deployment. Any way a massive destruction on any ground unit. Also a glass cannon that needs close quarter back-up. The rockets could be stopped by AA though.
- RLS, a structure that does high damage against air. But has a lower reload. 1 turn? So the player needs to think hard before deciding how many RLS will try to stop the first air strike.
- Rocket base, a structure that does massive damage, yet needs a lot of reload time. The rocket (not a nuke but strong) can be upgraded constantly until fired. Can be a game ender.
- V1-Soldier, infantry unit that fires a small rocket. Good against tanks.
- A tank that is stronger in defense then the German Pantzer. But no bonus of any kind.

China/Japan:
- Samurai, infantry unit, strong against infantry. Actually has good defense against anti infantry weapons that are not high in damage. Lets say a -1 on any weapon. So weapons with damage 1 do 0. Weapons with damage 2 do 1. etc.
- Ninja, infantry unit, strong against infantry. Has a chance in dodging any weapon. Yes, any weapon. Also can crawl, walk, run around enemy units. Confusing them. The unit that the ninja is close to can't do a thing and needs help of other units.

America:
- A tank that is weaker in defense then the German Pantzer. Has no bonus of any kind.
- The Howdoyoudowitzer :) Also a tank, exactly the same. Except this one has a longer range. Outranging any other tank. Thus a first strike. Does not work against rocket based weaponry. And does not work against the Howitzer.

Great theme for a deck builder! WW1 started with horses, and ended with fighter planes and tanks.

Airplanes were used a lot for reconnaissance at first, before they got into shooting at each other. If there are any hidden cards (in a deck or in a players hand), using planes for those effects could be cool.

These are definitely alternate reality units but I had fun dreaming them up.

Holy Roman Empire (Germans)

As we all learned from Raiders of the Lost Ark and The Last Crusade Hitler was fascinated with the idea of using the paranormal and occult as weapons (at least according to pop culture). What if he had succeeded?

The Geistkrieger - a brigade of paranormal specialist that is relatively defenseless but with a number of special skills including teleportation, temporary mind control over nearby enemy units, and a hefty spontaneous combustion self destruct ability.

What if the hindenburg had not gone up in flames?

The Dirigible Skycrane - a unit with the ability to transport large numbers of troops and artillery. Perhaps there could even be shielded "flying castles" fitted with long range artillery and anti aircraft.

The Soviet Union

I guess I am just on a blimp kick but...

The Sarancha - An inexpensive unit that is basically disposable airborne infantry. A few thousand soldiers strap themselves to mini blimps and black out the sky with their inevitable advance using hand launched bombs and sniper equipment to destroy targets below. These units would be super vulnerable but make up for it in sheer overwhelming numbers.

Russia's proto KGB spy network/Anti Soviet Rebels - This "unit" would be more like an ability where the Soviet Union player could roll a dice and have a 4/6 chance of converting an enemy unit (presumably having been spies all along) to its side and a 2/6 chance of losing a unit of the same type to their target's nation (as rebels). Obviously this would present some serious balancing challenges but I thought it was interesting for brainstorming's sake.

China/Japan

Chinese Rocket Infantry - Artillery Infantry combo unit that can do serious damage but has a limited number of rocket ammunition rendering it effectively just infantry after it runs out.

Japanese Mech. Samurai - Mechanical exo-suit that can be used by any samurai infantry unit (basically needs another unit to operate it) and is super effective against enemy infantry. The benefit to this is that while the pilot may die the Mech could be repaired and continue to operate. The stats on this unit would basically be that of a lightweight tank.

The Middle East/Ottomans

Parabolic Heat Beam Towers - ok i might be reaching a bit for this one but what if they had the ability to create towers that focused large amounts of sunlight on distant objects burring or melting them. (great defense against metal tanks when you can melt them as soon as they are visible on the horizon.)

For some reason I feel these guys are thematically more likely to use targeted poisoning, some sort of natural plague or some lost technology rather then high technology.

What about assassins, summoned sandstorms or locusts or some sort application of greek fire?

You could always have mounted camel units.

'Merika

I like the mobile robot production plant idea. What about the ability to entice other nation's scientists to America? Other than that I was thinking

GI Jetpack - Uses a Jet Pack using Pulsjet technology that was around during WW1. These guys would be less likely to zip around and hover and more likely to be able to launch themselves far into enemy teritory and then paratroop in. Could be useful in surgical assaults on the Soviet and German blimp units.

Good luck with the game!
