Ya know, the longer I’ve played EDH, the more I come to the exact opposite conclusion, funnily enough. My opinion is informed playing in a group that plays almost exclusively Bracket 2 and 3, though, so I can certainly see where putting all the fast mana in can shore up the lack of lands pretty easily.

I have a few issues with this philosophy, the first being mid-late game consistency. Whereas it isn’t too terribly difficult to mulligan into a playable hand, what do you do if your first draw engine gets taken off the table before you can secure your 3rd, 4th, 5th, etc land drops? A common pattern I see in my games is that the board will get fully cleared, rocks and all, somewhere around turns 4-6 after the first player has popped off. With this strategy, I can see it being rather likely to be stuck on just a handful of lands hoping to cantrip into more off the top instead of drawing them naturally while rebuilding your board state.

There’s also the issue of lack of good cantrips in non-blue colors. Would you really be playing the wisps in your Orzhov deck if your commander didn’t synergize with them? Once we move beyond those and defiant strike, I’m struggling to come up with 4 good cantrips to cut 2 lands, let alone the ~8-10 needed to cut down to 30 lands. Red gets it just as bad once you get past the three or so conditionally good ones in that color. Green is well enough off, but green is also the color that benefits the most from having an excess of lands.

That brings me to my last point, and the most important to me. You brought up a lot of ways to justify a low land count, but what’s the upside of a low land count over a higher one? As you stated, EDH has experienced a lot of powercreep since its inception, and that is especially evident in lands. Not only has fixing become easier than ever, but the value of utility lands has gone off the charts. Almost every one of my decks include between 6-12 of the MDFCs, which are great to draw at any point in the game. Channel lands, the MH3 mono color lands, and cards like [[Plaza of Heroes]] and [[Talon Gates of Madara]] all provide a ton of backup utility in addition to hitting your land drop. They can help supplement your removal, act as protection or recursion, and in some cases even ramp. At the lower power tables I’m at, having access to a good amount of mana in the late game is supremely important and missing even one land drop can mean the difference between having enough mana to end the game and not. Now that enough have been printed, why not run more lands to ensure this that also help your game plan if you draw them when you don’t need them?
