Introduction
Commander, also known as Elder Dragon Highlander or “EDH” is unique among MTG formats. EDH was created by the player base and is still managed by a rules committee of fans who are not employed by Wizards of the Coast. In fact, Wizards of the Coast did not release any products for the format until 2011 when they brought out a set of five preconstructed decks. Since then, Wizards of the Coast have released an increasing number of Commander focussed products. Every standard legal set is now accompanied by a few new preconstructed decks, and there have been several Commander focussed supplemental sets.
Commander has now become the most popular way of experiencing Magic: the Gathering. The influx of support from Wizards of the Coast has, broadly, made it a more powerful and fast-paced format than it was before. Cards like Dockside Extortortionist,
Arcane Signet



What is PreDH?
PreDH was designed by Brian David-Marshall. The idea is that it captures Commander as it was prior to Wizards of the Coast beginning to support the format. PreDH decks cannot contain any cards printed after New Phyrexia, the final Magic set which was released before the first Commander product came out in June of 2011. PreDH has the same ban list that regular Commander has, although naturally any banned cards released after New Phyrexia are already excluded from the format. This means no casting
Coalition Victory

Changes To Each Color

Many staple cards are longer available under the restrictions of PreDH. Every Color loses access to some of its best tools.
White players can no longer accelerate their mana as effectively without
Smothering Tithe



When this creature enters, if an opponent controls more lands than you, you may search your library for a Plains card, put it onto the battlefield, then shuffle.
. Draw options will also still be out there for Enchantment-based decks thanks to Mesa Enchantress and
Kor Spiritdancer

Whenever you cast an Aura spell, you may draw a card.
, as well as for Equipment-based decks thanks to
Puresteel Paladin

Metalcraft — Equipment you control have equip {0} as long as you control three or more artifacts.
.
Cyclonic Rift

Overload {6}{U} (You may cast this spell for its overload cost. If you do, change "target" in its text to "each.")
was first printed in the 2012 set Return to Ravnica, meaning that Blue players looking to bounce a lot of creatures will need to use
Evacuation

Black decks can no longer finish opponents off using
Torment of Hailfire


Red loses what is probably its best board wipe in Blasphemous Act and, arguably, its best card draw spell in
Faithless Looting

Flashback {2}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
. Both of these cards debuted in Innistrad block which narrowly misses out on being PreDH legal. Red players will have to make use of weaker alternative board wipes like
Inferno


Draw two cards.
and
Thrill of Possibility

Green players will no longer have access to
Craterhoof Behemoth

When this creature enters, creatures you control gain trample and get +X/+X until end of turn, where X is the number of creatures you control.
and will instead need to rely on cards like
Overrun


As long as this enchantment has seven or more quest counters on it, creatures you control get +5/+5.
to close out the game.
Cut Commanders

PreDH also features a significantly lower number of Commanders to brew decks around. There are fewer than 500 legal Commanders in the format, with no four-color options available at all. PreDH tables will feature Commanders like
Sedris, the Traitor King


Whenever Zur attacks, you may search your library for an enchantment card with mana value 3 or less, put it onto the battlefield, then shuffle.
rather than the likes of
Atraxa, Praetors’ Voice

At the beginning of your end step, proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)
and The Ur Dragon.
In addition, the Commanders that are in the format will have fewer options available to support the strategies they enable.
Rhys the Redeemed

{4}{G/W}{G/W}, {T}: For each creature token you control, create a token that's a copy of that creature.
decks will have to get by without
Anointed Procession


Some lesser known Commanders may also rise to take the place of big names that are absent from the format. Without
Krenko, Mob Boss


Sacrifice two Mountains: Create two 1/1 red Goblin creature tokens.
, or
Wort, Boggart Auntie

At the beginning of your upkeep, you may return target Goblin card from your graveyard to your hand.
Whilst all of these cuts may seem daunting, it’s important to remember the mantra of Magic’s lead designer Mark Rosewater: “Restrictions Breed Creativity“. PreDH decks will certainly not be as synergistic, or powerful as contemporary Commander decks, but this will open up new avenues for unknown or forgotten cards to see play. Will the slower pace of PreDH games make Plauge Wind viable? Will Serra Avatar return to the spotlight as one of the pre-eminent threats of the format? Is it Godsire’s time to shine? Who can say?
Conclusion
The meta of PreDH is still forming. In an article published for Star City Games Sheldon Menery, the head of the Commander Rules Committee, said that he: “would wager that there will be creature-heavy environments”. Whether this prediction will come true and PreDh will resemble Commander as it was in 2011, or whether players will design innovative new strategies using this pool of cards and the meta will evolve in new and unexpected directions remains to be seen.
In the same article, Menery writes that he intends for PreDH to evolve as an officially recognized sub-format with its own distinct ban list developing over time. There have been many Commander variants and other singleton 100-card formats over the years like Oathbreaker and Tiny Leaders. PreDH has received more support and recognition from the Rules Committee than these other formats. PreDH is designed to bring Commander back to its roots and that is certainly an appealing prospect to some MTG players.
