Good points :) The only thing I would make a note on is luck in card games: Some card games involve a lot more luck than others. One of my favorite iOS games, Orions, gives you a set of random cards (assuming you do a random match), and from there you play whatever cards you want (your full deck, basically, which is a random subset of about half the cards in the game). Of course, you have to build up enough mana to play a given card, and many increases by 1 each turn on its own. Its possible to be given a crappy deck, but even those matches you can play out more deterministically because you know what you've got to work with; also this is part of the fun - finding a creative path to victory with a deck that you are not used to (building decks can be fun in its own right, but I (personally) prefer being given a random set of cards - this makes each playthrough more unique and exciting).

In shorter words, there are a few types of luck you could work with: luck of the deck, luck of the draw, etc.
