Life from the Loam doesn’t make the cut in straight GW maindeck lists, it’s simply not required. There, it’s just a sideboard option against control. In Punishing lists, which have a much more fragile manabase and rely heavily on Grove of the Burnwillows to recur Punishing Fire, a lategame tool to recur lands is a key for the stability.
Maybe I wasn’t clear enough in my previous post. The list with Crucible you mentioned was played by Fabian Gorzgen. The same Gorzgen, the day after, chose to switch Crucible for LftL in the list he actually played to T8 the GP. Hence, the same Gorzgen came to the conclusion that Life from the Loam was better than Crucible of Worlds. The list you mentioned was just a final test, and is an outdated list.Quote:
I did guess that Crucible is in place of LFTL, but why the choice? Seems to have very little advantage over Loam in our context.
In fact, you never play Enlightened Tutor MD. It’s a sideboard option to improve your hate density, usually against non-blue decks.Quote:
Actually, I suppose thinking about it more those Enlightened Tutors are still there in the sideboard (...)
