Lately, I've been heavily involved in EDH deckbuilding and gameplay. It's kind of been ramping up and I'm having a lot of fun with the format. As I noted in some other recent thread somewhere, I don't want to turn into one of those people who basically quit the rest of Magic and become exclusively EDH players. I can see the temptation for it, but I think it's a shame. 60-card constructed with the traditional 4-card rule is what I still view as the default, the lifeblood of the game. Highlander formats are fun too, but they should not
replace the default. And I feel like I'm not really doing my part to bolster that conviction. I'm planning to do better, but that's a topic for another thread.
There's a huge gulf between having up to 4 copies of a card in a 60-card deck and having only 1 copy of a card in a 100-card deck. And that change applies not just to one card by itself, in a vacuum, but to the cards that work alongside it. There are deck concepts that, apart from any viability considerations in various 60-card constructed formats, aren't even
possible in highlander formats. Nether Void isn't the most extreme example of an approach that gets ruined in a highlander setting. Something like Squadron Hawk takes a bigger hit. But you can't use the traditional 90's Nether Void deck in a highlander format. It won't work.
In Canadian Highlander, I tried out a Pox-like deck that included Nether Void, but I was dissatisfied with the result. Unfortunately I do not have my list. At the time I built the deck, I was considering it an early draft and wanted to get some practice in, refine it, then post my decklist on TappedOut. But my black control deck with a green splash was so utterly trounced at every turn in testing that I kind of gave up on it, and the deck had
so many cards that were useful for other decks that I quickly scrapped it for parts, and that was that. I don't think that black control is unworkable in Canadian Highlander and although Nether Void is no staple in that format, I'd have been inclined to explore the idea further. It was just bad timing.
In any highlander format, the challenge with trying to make Nether Void useful is that you can't easily fall back on redundancy. There aren't really any other cards
like Nether Void. And the cards that make Nether Void good are also limited to single copies.
Hm, when I put it that way, it seems less subtle than it probably is. Nether Void might be a traditional build-around card, but so are other cards that are
amazing in highlander formats. Survival of the Fittest is a traditional build-around card, namesake of multiple archetypes and generally seen as a 4-of in 60-card constructed decks. But it's also great in highlander formats because the same deck that has SotF will also run Fauna Shaman, Green Sun's Zenith, Birthing Pod, Worldly Tutor, Chord of Calling, Eladamri's Call, etc. Paradoxically, the fact that there are a bunch of worse versions of Survival of the Fittest is good for the playability of Survival of the Fittest because you can reliably get some version of the effect, even if you don't draw into the card itself. The simple circumstance that WotC decided Nether Void didn't fit the color pie would go on to become a huge detriment to the card in highlander formats. Consider this fake card I made up just now...
Better Void
2B
Enchantment
Whenever a player casts a spell, counter it unless that player pays 3.
If that were a real card, it might make Nether Void obsolete in Legacy (there's the potential that it could become such a strong build-around that a Nether Void or two would get thrown as somewhat worse copies five and six of the card). But in EDH, you'd run both of them together and double your chances of getting the effect. Up to a certain point, the more cards in the general category of "black cards that make people pay mana not to get their spells countered" there are, the better Nether Void would be in highlander formats,
even if it was inferior to all of those other cards. It's not intuitively obvious that having multiple cards that do a job better makes a card itself more viable in deckbuilding, but that's how this often plays out. Redundancy is just that important. For a highlander playable, it's better to be relatively mediocre at achieving an effect you can reliably pull off than the all-star paragon of achieving an effect that can't be found elsewhere.
Now, it's not
all bad news for Nether Void in highlander formats. Despite everything I've said, the card is powerful. A 3-mana penalty is substantial and while opponents can eventually overcome it, Nether Void is an obstacle for just about anyone. A lot of old cards that were once powerhouses haven't aged well. And costing 3B in a world of cheap, efficient threats and answers isn't ideal (which is why no one ever runs it in Vintage anymore). But like I said, the card is powerful.
With my enthusiasm for Nether Void, I've been looking to run it in EDH. It seems that the most popular niche for it is unique to the commander aspect of the format...
At first glance, Mishra looks like a rather bad commander. You can't run multiple copies of your artifacts, so the ability has no value on its own. But Mishra effectively breaks the symmetry of Nether Void for your artifacts. Cast Sol Ring, stack Nether Void's trigger on top of Mishra's trigger, let Nether Void counter Sol Ring, then use Mishra's ability to put Sol Ring from your graveyard onto the battlefield. Your opponents all get slowed down by Nether Void and you had the foresight to pack your deck with lots of artifacts. Nether Void is just one card that Mishra's ability interacts with...
