give one inf + 4 range and vision +2 two and damage +50 %

TRAP
place one heavy and light tank for one turn next to a friendly unit

OPERATION SILENCE
give one mechanical unit camo for one turn. unit can not shot for that turn

Sorry caos, but alot of these cards are way too complicated, unbalanced, etc

Camelion Tank - there's already one or two multi-buff cards (berserk, tank leader). Instead, just make a Camo for ground mech units (and air units) that allows firing and costs... oh, 50g? Maybe a little mor

Undead - I would deffinately like to see some kind of revival card. How about: Revive a unit that was destroyed last turn. The unit has -40% armor. Cost is whatever the normal cost of the unit is (reviving it will spawn it on the same hex it died on. Does not work if the hex is occupied)
Also, change the name Undead, because that gives a fantasy-scifi kind of feel, which doesn't match this game's theme whatsoever

Blitz - interesting, but change it to 50% at MOST, and make 3 seperate cards, 1 for each unit type

Nebal Bomb - um... what? I tried fixing it up from what you said but i'm still confused

Magnet - take it and... what? Control it? Kill it? Move it?

Contract with the Dead - very interesting. I like this. Again though, the name must be changed

Weapon Upgrade - deffinately would like to see this

High Weapon Upgrade - No. Absolutely not. Artillery with 4 shots? No way in hell

Anti-Tank commander - I like the idea of a superbuff infantry that can't cap anything, but 1000%? No. 100%? Sure

ok i think BLITZ for ground unit and SKY AID for flights. i think for inf we have enough speed buffs

with NAPALM BOMB i mine a arty shot cart he make only 25 damage on the target hexes a unit they goes over get 25 damage for every hex he get

UNDEAD name change to LAST SURVIVOR

MAGNET move one unit from opponent or team pardner to your unit

Contract with the Dead name changed too LAST MARCH

i hope this make some better as before

EDIT:
NAPALM BOMB effect target the neighboring hex from the target hex too

I think with Nepal bomb you mean Napalm bomb?

Yeah he does mean napalm. Works like mines, but units start burning for some rounds.
-Op Silence: Pretty useless compared to airlift.
-Trap: the ground version of air support. makes sense.
-Blitz: It could really be a card that does +100% movement to all units for one turn. But it needs to be expensive, like 100g, so you have the speed advantage but a unit less than your opponent.
- Magnet sounds fun - but it's basically airlift enemy. It has to be restricted on something like 3 or 4 hexes distance with nothing in between.
- Sniper is great, but it should be something like +50%dmg vs inf but -50% dmg vs everything else.
I like all the other inventions.

FALSE TARGED (a anti baserush carts for 200 gold at least )
trade of the life points from your base with the oponent base

LAST HOPE
full repair 3 units after 3 turns the healing units died

GUN TURRET
plache one gun turret on the targed hex with 3 range 1 vision and 3 shot and 150 lifeponints unit can not move
damage vs ground 3-6 (18)
damage vs air 20 - 30 (90)
damage vs inf 18- 25 (75)
damage vs buildigs 1 (3 )

SPY
cup one tank faktory or airport

EDIT: Thanks hmpf for tip to make the cards better

I like sniper a lot. Cool idea. I think he should be permanently immobilized though for that range benefit

Deffinately. And possibly only works on elevation or adjacent to a non-movement hex (such as a tree)

HEKTORING 50 gold
send one oponent unit back to base

HEKTORNG+ 100gold
send two oponent unit back to base

Keep the ideas coming mrcaos. Some of these are quite good (some are not )
