There is this battle against the monster on the graveyard where you have to get 3 enemy cards at 1 hp (right after tutorial) and i cant figure out how to win it..
Whats even weirder is that the game says ive lost even if i still have remaining cards..
You've got to do a bit of maths to work out how to get their hp down without killing them.
The only way to damage them is with the arbalests.
Remember the arbalests do the same damage as the number of cards on their row.
You may also have to move some cards from one row to the other in order to get the damage dealt correct.
Spread the damage out so that you don't have 1 rotfiend left over who needs a little bit of damage and you can only do a lot of damage, therefore killing it.
Remember, you have to play 1 card each turn. If you run out of cards you'll automatically pass, and the enemy will win. You have to do these puzzles pretty quickly.
