There should be a way to mark a tile as "suspected clear" without actually clearing it. A lot of the puzzles don't have any apparent way to deduce any specific tile as being a mine or safe, but can be determined by picking one and seeing how it works out with all the hints, but it's really hard to remember what is clear and what isn't with your pick without actually clearing them.
Cold and Electric resist are more important against creator godcat than holy resist.
Also give Anna the flair that replaces weapon status effect with Doom and spam Arrow Rain.
@joker4375: When the horde attacks it forces a regular attack on your walls in addition to the horde itself. Meaning, all the zombies in squares adjacent to your walls will attack you, plus the horde.
Most stupidly powerful setup for the third area: Striker Penguin, Cold Collector, and Ice with an even spread between Impale, Swarm, Proficiency, Stasis. You barely even need the other 2 runes at all. Pretty much the only use is firing a Mjolnir every now and then to destroy the shield on the knights or make it easier to freeze the succubi, or shooting some accuracy + proficiency lightning at air units. Just hold down attack at the bottom right corner with Ice equipped and nearly everything dies eventually. They can barely move between the chill and the freeze and the reaper will eat them when they're frozen. The reaper will also destroy projectiles and do a pretty good job of getting rid of small air units.
Oh and ALWAYS fight if their strength is "low", you'll always succeed, and you get a permanent 10% strength bonus. Even if they have low cunning as well, fight, the bonus is worth the population loss.
Important note: your military strength/threat level has no impact whatsoever on how difficult incoming threats are. It only changes how often you're attacked. It is entirely feasible once you hit a critical point with Farming or Animal Breeding (where your population just starts exploding) to completely forego any defense at all (100% threat) because it's still reasonably likely that they'll be low strength or cunning and you can beat them, and if you can't you have your crazy population growth to make up for the losses.
Also "medium" strength or cunning is utterly identical to "high", with a 0% success chance. If there's nothing low, flee, it's your only chance of success.
@sirhc2003 uh no, no it wasn't. Advance Wars was released September 10, 2001. This wasn't even made before the most recent one (Days of Ruin) which was released January 21, 2008.
Mining is one of the best techs in the game to put multiple points in since it increases the effectiveness of your production workers. Unfortunately, higher-age production techs only increase the number of workers when you put more than 1 point in, which makes Mining generally be a better tech than the later production techs. Dump as much into it as you can before Copper Age.
Later on you really just set up a "formation" (really just a blob of all the ranged guys with warriors in front in a semi-sane manner) with the warriors, archers, priests, and mages to deal with the bulk of the enemies, and focus nearly all your time on controlling a pack of thieves that roam around assassinating things and helping out the warriors when needed.
@coyotik: No, the secret to the last level is to not even bother with the cart at all. Drop the ramp close to the rival vampire, destroy the cart, and then just let your vampire roll on down. Don't bother with the wedge or the cart, they aren't needed.

WASD kinda does that already. You can also hold CTRL instead.
