How to win:
1. Get a bunch of the same 5-dot letter (ex: X) in your boiler (throw in some special letters if you'd like)
2. Go online and get a list of words with that letter in them
3. Sort the list from shortest to longest word
4. Win!
Ridiculously easy. Your party can be fully upgraded about 1/5th of the way through the campaign... and then you run around doing fetch quests for the rest of the game.
If you go into options you can speed up battle messages - this means you don't have to wait as long for your cards to attack!
Also, I found purple overpowered - just spam power drain and myrkin spies and the enemy can't do anything. The Land of Plenty card is great for the 1 hp and 100 hp levels.
