Go Epic (EDH / Commander)

Premise
Going Epic is like ascending to godhood, but why be a demigod when you can be Zeus? [[Eternal Dominion]] and [[Undying Flames]] reward you by copying themselves every turn after you cast them just once, but you have to pay the Epic cost: no more other spells. Once you commit, there's no going back.

However, if you copy an Epic spell, the Epic ability will take effect multiple times. Two instances of an Epic spell that resolve one after another will cause you to copy the first one on each of your upkeeps minus its Epic ability, and also copy the second one on each of your upkeeps minus its Epic ability. Both prevent you from casting spells, but that was already going to happen anyway.

So if you put N copies of an Epic spell on the stack and they all manage to resolve, you'll be getting N copies of that spell on every following upkeep!

Commander Choice
The other 3 Epic spells don't really win you the game so easily, so the deck had to be blue and red. There are a few other commanders that seem good, the best one being [[Zevlor, Elturel Exile]]. However, my friend already has a [[Zevlor, Elturel Exile]] deck and I wanted something new. [[Narset, Enlightened Master]] is great because she allows the high-cost Epic spells to be cast more easily. In addition, [[Undying Flames]] requires the deck to be filled with high mana value cards, which work well with [[Narset, Enlightened Master]].

Play Pattern
The deck relies on the commander pretty heavily. [[Narset, Enlightened Master]] can come down pretty early with all the ramp in the deck. Ideally, she can be played on turn 3. Then she has to survive long enough to attack. This should be doable since she has hexproof, but in case of emergency the deck has [[Force of Will]] and [[Fierce Guardianship]] to protect [[Narset, Enlightened Master]] and to protect against the combo being countered. Once [[Narset, Enlightened Master]] attacks, hopefully that leads to a win. I would consider this deck to win if you can create more than 3 instances of an Epic spell. With just 1 or 2 [[Eternal Dominion]]s, you mat not be able to put yourself into a winning position fast enough, especially since this deck does not play defense very well.

Notable Cards

• [[Eiganjo, Seat of the Empire]] and [[Otawara, Soaring City]] can still be channeled after going Epic. This potentially allows for some amount of interaction both before and after ascension. For example, [[Otawara, Soaring City]] can bounce [[Lavinia, Azorius Renegade]] and allow the Epic copies to resolve for a turn.
• Similarly, [[Celestial Colonnade]] can be activated and can attack even after going Epic.
• Double-faced lands like [[Emeria's Call//Emeria, Shattered Skyclave]] and [[Sea Gate Restoration//Sea Gate Reborn]] can create good hits off [[Narset, Enlightened Master]] and also work well with [[Undying Flames]].
• [[Generator Servant]] is cool because it gives [[Narset, Enlightened Master]] haste while ramping into her.
• [[Errant, Street Artist]], [[Strionic Resonator]], [[Twinning Staff]], and [[Lithoform Engine]] can all also be activated after going Epic and can target the Epic-generated copies. This means that for example one [[Errant, Street Artist]] can copy an Epic spell when it is first copied and has not resolved (i.e. on the combo turn) and then continue to copy the Epic copies on subsequent turns.
• [[Strionic Resonator]] can copy [[Narset, Enlightened Master]]'s attack trigger.
• [[Paradox Haze]] will double the number of Epic copies generated each turn.
• [[Radiate]] can generate an insane number of [[Undying Flames]] copies when it itself starts to get copied, since it can target each player, each creature, each planeswalker, and each battle.
• [[Thousand-Year Storm]] is the most silly card because when you go Epic spell into [[Fork]] into [[Twincast]] or something, you will be getting a ridiculous number of copies in some cases. This enchantment is therefore a critical part of going huge in this deck.
• [[Enlightened Tutor]], [[Mystical Tutor]], [[Personal Tutor]], and [[Long-Term Plans]] will all put the cards into [[Narset, Enlightened Master]]'s reach so she can cast them for free. [[Enlightened Tutor]] finds [[Thousand-Year Storm]] or a mana rock in the early game. The others can find a wider variety of spells, including the Epic spells.
• [[Ancestral Knowledge]] and [[Scroll Rack]] can also help stack the deck in [[Narset, Enlightened Master]]'s favor.
• The extra combat spells help with getting a larger mass of [[Narset, Enlightened Master]]-exiled spells available in one turn. Note that these spells untap creatures when they resolve, so copying them usually isn't very lucrative.
• [[Irenicus's Vile Duplication]] copies [[Narset, Enlightened Master]], which gets nasty if this spell itself gets copied. Attacking with 2, let alone more than 2 [[Narset, Enlightened Master]]s starts to get disgusting.
• [[Aqueous Form]], [[Dolmen Gate]], and [[Inviolability]] allow [[Narset, Enlightened Master]] to attack with impunity. There are other cards that do this in the sideboard/maybeboard. These were chosen because they are cheap manawise. [[Dolmen Gate]] is also not an aura, which is nice.

Extra Turn Spells
The traditional builds of [[Narset, Enlightened Master]] decks include a lot of extra turn spells because they are great hits off [[Narset, Enlightened Master]] when you can cast them for free and then get another attack trigger on the following turn. I wanted to shy away from this a little bit and see if the deck can function without these extra turns. Plus, if an Epic spell gets exiled along with an extra turn spell, it's not so good since the Epic spell will be lost forever and the extra turn will not help in that case. There are 2 Epic spells in case of this occurrence, but still it may not be so great to just take all the turns. They do provide lots of high mana values for [[Undying Flames]] though. Perhaps more of these will come in later.

Note on [[Undying Flames]]
I worry with this card that it will exile the entire deck without killing everyone...

A more focused build of the deck probably involves going more all-in on a few copy spells, like mainly the disgusting ones like [[Thousand-Year Storm]], [[Storm King's Thunder]], [[Twinning Staff]], etc. and dropping [[Undying Flames]]. [[Eternal Dominion]] should already be enough to win with, and I think the deck could be more streamlined. This would also allow the average mana value to come down, since it has been kept kind of high right now on purpose to support [[Undying Flames]]. Other cards like [[Aminatou's Augury]] and [[Dance with Calamity]] that cast multiple spells would probably be suited for the [[Thousand-Year Storm]]-style build.

Mana Notes
There are more islands than necessary in an attempt to support [[Mystic Sanctuary]].

Sideboard/Maybeboard Notes

• Card draw/filtering would be nice, but I didn't think there was much room. [[Brainstorm]], [[Ponder]], [[Preordain]], and [[Serum Visions]] all help set up the top of the deck for [[Narset, Enlightened Master]] too. These would likely be good additions to the deck.
• There are some extra copy spells and tutors here.
• There are other card draw/filtering options.
• Other ramp cards might be good to have, seeing as the main point of the deck right now is to ramp into [[Narset, Enlightened Master]] quickly and win from there.
• I kept the board wipes out for now because killing off [[Narset, Enlightened Master]] is such a huge blow. Cards like [[The Eternal Wanderer]] are great here. Should also consider [[Divine Reckoning]].
• [[Cyclonic Rift]] is great, but not a great hit off [[Narset, Enlightened Master]]. Probably should still be in the deck anyway, but I'm not sure.
• There are also other attack enablers in here, but I thought the few in the deck would be enough because they don't get better in multiples.
• [[The Mirari Conjecture]] seems great for this deck, but the copy chapter is too slow and there often aren't good spells to get back in the early turns.
