"Urza, Annoying Artificer"
Finally getting around to putting my Urza deck on Tapped Out. The Paradox ban basically killed Arcum so lots of the pieces from there were shifted into this.
===accordion
===panel: Combo List: Arbitrarily Large Mana
Combos are:
[[Grim Monolith + Power Artifact]] = Infinite colorless mana
[[Isochron Scepter + Dramatic Reversal]] + 3 or more from mana rocks = Infinite mana (usually blue because Urza makes his own mana rocks).
[[Proteus Staff]] + Urza's Construct token pulls Tidespout Tyrant from the library, guaranteed. You can then play a spell to return a 0cmc rock to hand, and bounce those rocks to produce extra mana. A 0cmc and a 1cmc rock also produce infinite mana, as well.
[[Polymorph]] + Urza's Construct token = same as above.
===endpanel
===panel: I Have Infinite Mana, Now What?
Your first goal will be to exile your library with Urza, and play [[Narset, Parter of Veils]] with [[Windfall]] or [[Echo of Eons]]. This will strip your opponent's hands down to 1 or 0 if you do it more than once.
After that, where you go from here depends on what cards you've used up so far this game, what was removed, etc..
Generally speaking, safe routes are establishing Echo loops, playing [[Isochron Scepter]] with [[Dramatic Reversal]] or [[Narset's Reversal]], and cloning your Scepter with [[Copy Artifact]].
You can also loop [[Echo of Eons]] with [[Isochron Scepter]] imprinted with [[Narset's Reversal]], or if Scepter is gone you can loop Echo of Eons with Codex Shredder so you can loop your instants and sorceries.
===endpanel
===panel: Okay, So How Do I Win?
There are a large number of win lines you can perform once you've exiled your library and stripped your opponent's hands to nothing.
You can freely mill your opponents with [[Codex Shredder]] when you control Dramatic Scepter, and then you can cast [[Windfall]] to deck your opponents (you can control the side of your library by casting instants/sorceries with Echo, so you'll never deck yourself!). You can also deck your opponents if they control a creature by using Reality Shift in Echo of Eons loops.
You can finish out the game by generating infinite bird tokens- you can play Dramatic Scepter, then copy Isochron with Copy Artifact and put Swan Song on it. Play literally any spell Swan Song could target, then activate the Swan Scepter, then Dramatic Scepter which untaps the Swan Scepter, then activate Swan Scepter again to counter the first Swan Song, yielding 1 bird token for you. Repeat this process until your board state looks like an Alfred Hitchcock movie, and then attack the following turn (again you can control the size of your library by casting your instants and shuffling them back in with Echo, so you won't deck yourself).
You could also loop playing artifacts to generate infinite thopter tokens with [[Sai, Master Thopterist]], using bounce spells, Echo of Eons, and Codex Shredder/Isochron Scepter+Narset's Reversal.
You can even bounce Urza with Chain of Vapor, re-cast him to make another Construct token, then shuffle the bounce spell back in with Isochron + Narset's Reversal and Echo of Eons, or Echo and Codex Shredder loops.
Effectively, you can loop any instant or sorcery in the library with Echo of Eons and some way to put it back to your hand. You can cast Echo then hard cast Narset's Reversal on it- Reversal would be shuffled in, Echo would be in hand, and you can once again re-exile your library again to cast all of those spells. You can put Narset's Reversal on an Isochron Scepter or copied Scepter to continually copy Echo, or you can just copy Echo and then bring it back via Codex Shredder, then let Echo shuffle that back in.

<strong>No Urza:</strong> If you can't cast Urza, he's been removed somehow ([[Gilded Drake]], [[Song of the Dryads]], et al), you can still draw your library by assembling [[Isochron Scepter]] + [[Dramatic Reversal]] + [[Sensei's Divining Top]]. You can just stack the Top draw triggers and activate the Scepter in response. You could also assemble Dramatic Scepter and Codex Shredder to mill opponents out.
<strong>No Scepter:</strong> If you don't have [[Isochron Scepter]] (it got exiled for whatever reason) but still assembled [[Power Artifact]] + [[Grim Monolith]] or something and have Urza, then you can't mill with Shredder, but you can still do infinite spell casts. By using [[Codex Shredder]] and [[Echo of Eons]] with any other spells, you can basically get the same result with a lot more steps. You can strip your opponent's hands with [[Narset, Parter of Veils]] and Echo, looping Echo via [[Codex Shredder]] and Urza's ability. You can loop any instant or sorcery, as well, even without Isochron Scepter (for example, just cast any spell and counter it with your own Swan Song, then cast Echo to shuffle it back in. You can loop Echo of Eons by casting Narset's Reversal targeting it (Reversal would be shuffled in) or loop Echo via Codex Shredder).
<strong>No Codex Shredder:</strong> If Shredder gets exiled or there's a [[Rest in Peace]] on field, you can use [[Isochron Scepter]] + [[Narset's Reversal]] and [[Copy Artifact]] (on [[Isochron Scepter]]) + [[Narset's Reversal]] to copy everything for the Echo of Eons loops and keep them all in hand, no need for Codex Shredder. You can go Bird/Thopter token beatdown route, here (in this circumstance, you just cast a bounce spell on a random artifact of yours, copy it with Narset's Reveral to keep it in hand, and then replay the artifact. Hooray, 1/1 Thopters via Sai!). Alternatively, you could just bounce the Rest in Peace and go about your business normally, but this is worth mentioning in case you can't target it for whatever reason.
<strong>No Echo of Eons:</strong> Losing Echo isn't a huge deal. It's a way to cast every spell from the library, but you can still win via Codex Shredding opponent's libraries and then [[Windfall]]ing them if you left enough cards in your own library, but if that's not an option (because Echo is how you control the size of your own library in the event important win condition cards are on the bottom), you still have access to infinite bird tokens by utilizing [[Isochron Scepter]], [[Dramatic Reversal]], [[Copy Artifact]], and [[Narset's Reversal]].

After playing this over the last few months, I've come to the realization that this deck is basically replacing my old [[Captain Sisay's Engine Chain Extravaganza]] instead of my [[deck:arcums-asylum-3]] deck. This deck plays a lot more like a more reactive [[Captain Sisay]] than Arcum, but that's by no means a bad thing as the Captain was my favorite cEDH deck.
