My two favorite LCG's so far have been Android: Netrunner and Star Wars: The Card Game . But the more I think about the resource mechanic in Marvel Champions, the more I like what it fundamentally does in this game as opposed to other LCG's.
When playing Netrunner , if you wanted more cards or money, you'd have to spend your clicks to get those (excluding the Corp's mandatory draw or any card triggers like"at the start of your turn" abilities, of course). But you only go through your deck once, so you don't want something that forces you to go through your deck too fast (lookin' at you, Noise!).
When playing Star Wars: The Card Game , you also didn't want to go through your deck too fast, but that was hardly ever a problem. Instead, you'd want to find the awesome cards in your deck as fast as possible. Drawing back up to your hand size in the Draw phase of your turn helped you do exactly that. But you would use tokens and resource generating cards to pay for things.
Now with Marvel Champions , cycling through your deck to get the awesome cards as fast as possible and generating your resources are one and the same thing. So the more resources you have on individual cards, the slower you go through your deck; and the fewer resources you have on individual cards, the faster you'll go through your deck. That's a very important thing to keep in mind when you are deckbuilding, and I am very much looking forward to deckbuilding because of it.
