Anyone that thinks that a top 8 performance in 7 round events is a solid metric for card/deck playability should know about the time I made top 8 of a 65 player event with 4 Shardless Agent, 4 Daze, and 0 ways to manipulate the top card(s) of my library in my maindeck. That deck was trash despite this result and the win I got at a 20 person Mox Pearl event.
That reminds me a deck that I saw. When broodbraid elf was released, a person played a 4 BBE, lands and singletons.
He won the tourney.
To me it's more about how busted the deck is. If the deck has a 14% metagame share with other decks having to pack 7-10 dedicated slots to play against it, it's clearly warping the metagame. Dredge is the deck we kinda get used to waste 6 sideboard slots. Pre-ban the sideboard had to be 12-14 slots for dredge and artifact.
About the 'island' comment, you should compare island to wastes. When we see a land with 'tap to add UUU. Use this mana only to cast instant or sorcery spells' it will make sense. Mishra's workshop has made a lot of cards get restricted so that it doesn't need to, and that's a pretty loud fact.
Jejeje... It was only a "joke". But, it's funny that Manu people are speaking about highlander mud, when blue decks are commander decks with 4 fows since... when? 2008?
The version i'm thinking about has some more lands, 4 dakmor + 4 paradise + 2 "free slots" (It could be petrified field, riftstone portal, wasteland and strip mine...) And 4 Diamonds.
As I said, it's more combo focused, but It has 2 FoV, though It could be 4 (i'm afraid not having enough green cards)
In the fatesticher version, LED it's the best card you can draw, apart of bazaar. It lets you dredge from t1, and unearth fatesticher. That's a 95% chance of T1 win. I don't know why you would play any other rock over it.
With London mulligan, I'm thinking in play full set of mox diamond and dakmor savage, in addition to the 4 mana rocks (Lotus, LED, shapphire and petal). Obviously it's even a more combo version, with less interaction.
