ProsBloom After initially deciding to start a Memories thread for LED, I was brainstorming and thought, "Well, it was in ProsBloom at one point." No, it wasn't. Not as far as I can tell, anyway. Not in tournaments. I was mistaken because I used it in ProsBloom in casual play, many years after ProsBloom was but a distant memory in tournament Magic. I forget how much I've emphasized it, but I've never really been good at the whole deck-brewing thing. It's not that I've never done it or can't do it, but I'm certainly not prolific about it. I think my decks when I play Limited formats are probably fine, although I'm not an experienced drafter. And I don't get to play as much as I used to in the past, so I might be a bit rusty. But even at my hypothetical peak, whenever it was, making a new deck from scratch was just not my strong suit. This was where Al0ysiusHWWW and I made such a good team: he has a good sense for deckbuilding and once I have a deck in my hands to playtest, I can be very thorough about deck refinement, exhaustively examining lines of play, matchups, and fine-tuning both the decklist and my playstyle to optimize winning. Nick's true passion was for control decks, prison decks really, but he liked variety. He was into combo decks. The problem was I already had a leg up on that. I owned more of the really good combo cards than he did. Later, he'd catch up. But in the years while I was blowing games out with Tolarian Academy, High Tide, Pandemonium, Sliver Queen, and so on, he methodically sought out combo decks for which I didn't own the cards. Sometimes, he found something good, like when he mastered Krark-Clan Ironworks. Other times, he hit road blocks, like when he put in work on a Recurring Nightmare + Palinchron infinite combo deck only for me to inform him that the "free" spells from Urza's Block had been hit by power-level errata specifically because of the Recurring Nightmare + Great Whale combo that had overtaken Standard before he'd started playing Magic. And still other times, he focused on things that were just plain silly, like Lure + Basalt Golem. At some point, he noticed that he owned more Mirage Block cards than I did and when the topic of ProsBloom came up, we decided to build it for him. Lacking his deckbuilding imagination, I pretty much went with stock lists from the deck's tournament history. But this wasn't a Standard deck: it was a casual deck! Nick kept the important, core cards of the deck, but added things like Lotus Petal, Meditate, Stormseeker, and oh yeah I already talked about this. Well, he also threw in Lion's Eye Diamond, at a time when the card wasn't really recognized as good. We both played his Storm Seeker ProsBloom deck a lot and it was one of the most fun combo decks I've ever played. LED was not vital for this deck, but we found it practical in a lot of cases, especially when we could tutor up and draw into blue card-drawing spells. Along with Lotus Petal, it gave a source of blue mana to keep Prosperity chains going while Cadaverous Bloom gave us all the black and green mana we needed. Perhaps more than anything else, this deck is what motivated me to blather on for so long about a simple mana-producing artifact. Our LED-using ProsBloom was built before Scourge enabled the card to take the world by Storm, but after its odd appearance in Broken Jar decks, so perhaps it wasn't coming completely out of nowhere. We didn't even rely on LED. But we found it to be practical. And it was considered a bad card. It was in the same set as other ProsBloom staples, such as Cadaverous Bloom and Infernal Contract, but the pros didn't elect to use it. A few years later, we did, and we liked it. Now, our deck had some advantages because we weren't constrained by the Standard card pool. This is an important distinction. Still, I can't help but wonder! Maybe the Standard card pool that gave rise to the original ProsBloom couldn't really exploit Lion's Eye Diamond. The pros certainly never saw it, and I'm sure they spent more time on this stuff than I ever did. I can't rule out the possibility that I'm just engaging in wishful thinking here, that the card didn't yet have a viable niche. Taking advantage of LED in an environment without Yawgmoth's Will, without Demonic Tutor, without Wheel of Fortune, without Memory Jar, and so on, the "discard your hand" clause really starts looking like a crippling drawback in a small cardpool. There are still options, things like Three Wishes, Vampiric Tutor, and Infernal Contract. But this takes some doing. It's not an automatic, obviously broken thing. I admit that this is starting to look rough. But here's the thing: the old ProsBloom was already pretty bad. Somewhere, I remember seeing a play-by-play of one of the matches with Mike Long piloting the deck, and he did nothing to affect his opponent for the first seven turns. Seven. That's how slow the environment was. Don't get me wrong: Mirage Block did contain some very cool cards. Lion's Eye Diamond was one of them. But the environment it created was agonizingly slow. Combo has come a long way since then. Magic as a whole has come a long way. You can't expect to sit around doing nothing and go for a turn eight kill. It doesn't work. I don't think that I can prove that LED would have been an improvement, but I strongly suspect that it would have been.
