1. In Naval battles, most of the time, my Big Ships shoot their artillery at the bottom of the screen constantly...
2. I think you should make it a little more obvious that in certain battles, you can build every type of Infantry/plane/artillery all at once.
Pokemon was not the first card game, nor is it the best. Also, Pokemon is for 12 year olds.
This game has some unbalanced cards, which are way overpowered, or useless, but if you play with a Random deck you can get a good game against anyone once you figure out a good strategy.
However, without having a hand of 'Effect' cards to play, there is not enough variance in this game to keep it interesting.
