I found this to be fairly incomprehensible. This absolutely needed a tutorial (or at the very least, each info bullet point on its own screen with visuals).
Game terminology is fairly inconsistent and not self-explanatory: the Peacock card states "Gain 1 wind NRG if your opponent controls more cards than you" even though the wind NRG is called "air NRG" by the basic land (?) card. Also of note is "controls more cards than you": is this cards in hand? a card in the loop? in Magic at least, controlling a permanent is pretty well-defined, so the vagueness really hurt my comprehension of the game rules and deckbuilding.
Even when I said "screw it" and built a garbo deck of my own, I really had no idea what I was supposed to be doing, let alone the right ratio of lands to creatures (if a distinction like that is even important). Preset decks would have been really nice to have to learn by example.
