Its not new to say this is one of the best cards ever printed, its not even really original to say this is a cornerstone of survivors to this day, both are things I feel strongly about but today I want to say something else great about lucky.
Its one of the first and best examples of a card that wins you the game by doing nothing at all besides changing your approach while its in your hand.
I have many times run lucky and held it back in my hand for rounds, sometimes half an entire game, never committing very highly on tests, sitting at a gentle 60% pass rate and never actually failing to a point where it would matter, the sheer amount of energy you save, the resources, the cards and the mental strain to just play super reckless and worry about the consequences later, you will win so much faster playing that way if your luck is at least marginal.
I can't count the amount of games I've ended with a lucky in my hand staring at me, gathering dust and looking back at how demolished the level was.
Its gotten to the point where lucky is SO good at making me win, I don't even include it in decks any more, it is perhaps to me is the only card in the entire game that simply by having had it in a previous deck (and no longer running it) I still get a massive benefit from it, simply by allowing myself to experience that risky, devil's gambit play style.
Lucky, it used to make me win games by sitting in my hand doing nothing, now it sits in my collection, and still is making me win games.
I'm curious what other cards can say the same for other players.
