Great tips Brute!

I'll add that for the first game, rounds 1 and 2 poking the enemy tank with the aqua doesn't make much sense as the tank will more often than not put up some kind of shield in the first few rounds. I'd save the cards and energies spent for later parts of the game.

You should experiment and practice skipping turns more often in order to make the enemy waste more cards/energy while you gain both.
