I think either card in the way it was described would be good but I think there is something else to consider.

Introducing a bomb card would introduce new strategy there is no doubt about that. Also, it is easy to understand how to use, someone has a big stack you can't beat, bomb it. It focuses on the number of armies and income of your opponent. This makes it very cut and dry leaving the only real strategy as to when to use it.

On the other hand, the time travel card changes nothing of income or armies but deals with knowledge. I think that this would allow for a lot more advanced strategy, not only including when to use it, but what to do after. Will your opponent change and how? It goes back to the whole idea that knowledge is power. The down side is that some people would use it improperly and you could run the risk in team games of replaying the same turn over and over again (unless there would be a 1 use per turn limit....?)

It really depends what you want to have:

Something simple, understood by many
or
Something versatile, that few will use its true full power

Hmm, I thought a bomb card would be more like a landmine of sorts (defensive card). I think what you are describing is more of a bombardment (offensive).

I think the timetravel card is so overpowered it is gamebreaking in most strategic templates

The use of it proposed by Mercer is very reductive

We already have a time Travel cards, they're called Order Priority and Order Delay, and they're awesome.
I like the idea of Bomb card though (I assume %armies killed can be adjusted, like any other card).

Perhaps a Time Travel card could be used as you suggested but it can only be out in practice games.... This would work great for tutoring as you can explain what someone did wrong, what they should have done, and then repeat the turn so they can ACTUALLY see it happen and gain better understanding....

Make it mutualistic^^ Both players have to agree to replay the turn?

Make bombs just change to Neutrals. Maybe certain types of bombs do certain damage if not just a normal bomb card.

Pls do the bomb card!

Alternate implication of time travel card that maintains original strategic value :

It turns a territory into the same state it was in during a previous turn.
At first, this might be seen as a free victory for a defender.
Buy it's a previous turn, not the previous turn.
Bring back a lost army for quick reinforcements, break an opponent's bonus by making it neutral or create a buffer from a strong attacking army.
Bombs should work like landmines : attack it and lose a percentage of armies.

Time travel:

This may be too powerful, but what if you could move armies around without the aspect of time: I've got a stack too far away; use the time travel (or teleport, similar thing) to defend a different area

Also, what if you could move a stack from the past to defend for 1 turn? This could also become too powerful.

Like an airlift card? Lol

Neither :)

I guess if anything bomb card is slightly more reasonable - but time travel? seriously. Why not have deploy X-men as well?

I really hope this is a joke.. ok, whatever, just don't add those "inventions" to any official ladders.

in strategic games,i think time travel card has no other use than delaying the game and reducing the requirement to think in tough positions,its a huge turn off
@mercer
in diplo games,i like the idea of time travel card
also in case of bomb card since we mostly need it in the adjacent territory,long range card can only be useful in diplos,not much point in having long range card in 1v1 or team games anyway

i have a new idea:how about if we're able to take control of the game from a specific turn after the game ends to see how the game would have progressed in that variation?
this is done in many games including chess,starctaft,dota,etc
ofc the results won't change,but it'll be a very awesome gaming experience :)

What if the bomb killed 50% of the targeted territory's armies. It would be a strategy to have more medium stacks instead of one big stack.

this card might be fun in rp games, but it will be extremely unbalancing in casual games. Do you think big stacks are an issue, a specific card should deal with?

Time Travel card is used at the end of a turn. The turn is played as normal, but at the end, all changes are lost, and you start that round over again (Ground hog's day the movie). However everyone would have seen deployments and attacks occur. Everyone would know the outcome of the round if they continue to play that round the same way next time.

Im not sure if I got you right: the turn happens and is undone afterwards, for everyone? which means you only delay the entire game with this card? sounds pointless to me... In fact I will see the outcome of my alliances, with or without the card

I guess there are other suggestions for new cards, that are way more usefull. I would rather suggest a fortified position card, that gives a territory a bonus in cases of defense. which would be similar to the abandon card, but without the disadvantage of turning your units into neutral stacks.
Or maybe a decoy card. If you play this card, your territory will display your opponents a fake number of units ...

Anyways, Im pretty sure there are several things more valueable and worth an upgrade (for example: more informations on the map and profile pages).

I like the Bomb card idea...

Question on time travel. How would it deal with players that have been booted?

the turn never happened,players getting booted comes in the orders panel in the game,so they don't get booted

Bomb card should be renamed "Air Strike Card" and should include limited long-distance such as three territories away. %armies destroyed should be adjustable.

Neither.
