Prototype Portal Discussion

why not add Prototype Portal with maybe Phyrexian Metamorph. Make a xerox machine for copying creatures and artifacts both on your side and theirs.

Thanks! You're right about the Bracers' potential. I'm planning to slot in an Aphetto Alchemist to take advantage of that, since he goes infinite with basically anything at that point.

The Prototype Portal is mostly a goodstuff card. It can be handy for ramping up, redundancy for the Myr Reservoir (the weakest point of the combo, honestly- it's the only part that doesn't have some kind of redundancy), getting 5 blockers per turn with a Myr Battlesphere in there, whatever. It was one of my earlier rares I ever pulled, so I've got it in there as partly nostalgia even.

You hit it right on the head with this deck not needing to win all the time. It's so much fun to durdle with that you won't really care much if you only win 1 in every 10 games or so. That said, this deck relies heavily on card draw to assemble pieces. If you are planning to add counterspells, I would recommend something that refills your hand somewhat as well, just to dig down a little further.

Jin-Gitaxias, Core Augur also falls in that "goodstuff" category for the most part, except that he digs for combo pieces hard, and can disrupt their answers by discarding them all. Cyclonic Rift would probably be a better choice, but I already run enough of those in other decks and didn't want to flood my meta with more.

I would say run with it! Your alterations look like they could be a lot of fun. And if you do end up building and playing the deck, let me know how it goes! (And if it isn't too much of a bother, credit me with the original idea. I'm pretty darn proud of this thing. :D)

  1. I think this rule will tell what you need for this one. 301.5c An Equipment thats also a creature cant equip a creature. An Equipment that loses the subtype Equipment cant equip a creature. An Equipment cant equip itself. An Equipment that equips an illegal or nonexistent permanent becomes unattached from that permanent but remains on the battlefield. (This is a state-based action. See rule 704.) An Equipment cant equip more than one creature. If a spell or ability would cause an Equipment to equip more than one creature, the Equipments controller chooses which creature it equips.

  2. Yes. Provided that the right creature types are there, Mairsil can advance to the 8/8.

  3. He would not. Kazandu Tuskcaller and other levelers do not have the other abilities unless they have the right number of counters.

  4. Yes he can, there's no issue with that ability.

  5. No. Prototype Portal's ability is linked specifically to the card that it exiles when it enters the battlefield. Cards exiled by the ability from Myr Welder will not be able to be copied, despite both abilities coming from the same source.

1 I cast Mairsil, the Pretender exiling Demonmail Hauberk with a cage counter. It's my only creature. Can I sacrifice Mairsil to try to equip it to itself? Can I sacrifice another creature to try to equip him to himself?

Just a note: the Gatherer page seems to state that you can activate equip abilities, but Mairsil doesn't attach.

2 If Maersil exiles Figure of Destiny can it become the 8/8 Kithkin Spirit (eventually)?

3 If he exiles Kazandu Tuskcaller, can he tap to make 2 Elephants even though he has no level counters? Also, if I cast Venerated Teacher will Maersil gain level counters?

4 If he copies Mischievous Quanar can he facedown himself?

5 If Maersil exiles Myr Welder and Prototype Portal with Cage Counters. Can he use Prototype Portal to copy cards he exiled with Myr Welder's Imprint?

okay! what you say about Welding Jar is right! i use it because i have some boardcleaner in my deck an i forgot it X)

Dispatch is the same like Thoughtcast: there are other cards doing the same but more consistant... in this case Silkwrap, Journey to Nowhere or classic Oblivion Ring.

before you reach the point where Tempered Steel becomes usefull, you need more than just Myr Battlesphere to get more than 1, maximum 2 myr each turn. for this reason Myr Matrix becomes much more interesting than Myr Turbine... Ring of Three Wishes or Citanul Flute are better (in my opinion) than Myr Turbine because you dont need to tap a lot of creatures which are needed for more important quests... and there are a lot more cards which let you search your library for a creature.

here is a small list of cards you should know and maybe you can make something awesome out of it ;)

Soul Foundry

Prototype Portal

Sculpting Steel

Ghostfire Blade

Myr Welder



Buried Ruin

Darksteel Citadel

i notice that there are not so much cards who throw out myr weenies other than Myr Matrix, Myr Turbine and Myr Battlesphere... or crap cards like Myr Sire

You can use double square brackets to link cards. It's the easiest way to make sure everyone understands the details of what's going on in your question: Kaho, Minamo Historian, Withered Wretch, Prototype Portal, and Mairsil the Pretender isn't in the database yet so here's a link

No. Rules-wise, the phrasing "copy of a card exiled by Prototype Portal" is functionally identical to its current text. The reason Prototype Portal is written that way is because under normal circumstances there will only be one card imprinted on it. Pairs of linked abilities can only be linked to each other, not to anything else.

MadHatter23, Platinum Emperion is an AWESOME card. If only we had some one-sided way to abuse his "can't change life total" clause! Maybe Sulfuric Vortex?

dlamars, makes sense! Likewise, Staff of Domination + Metalworker and 3 artifacts in hand will create infinite mana and draw the deck too!

So, I've been testing the deck against other competitive decks. I was unhappy with how it was performing. If people left me alone for a bit the haymaker value engines like Ugin's Nexus + Prototype Portal + Daretti's for tons of extra turns, ramping into Devastation / Jokulhaups with Daretti in play, or Goblin Charbelcher + Unwinding Clock provided great, fun, powerful win cons. The problem is, truly competitive decks seldom let any of these things happen. I've also found that while Daretti lends himself to a strong stax/reanimator theme, I'm not sure I've got the deck built as ideally as it can be. The reason I say this is, while reanimator decks tend to have a higher curve that normal, stax decks require a very low mana curve in order to be able to function under the effect of your own taxes. While having tons of 5+ CMC spells is great for the reanimator theme, it is terrible for the stax theme. Many folks have pointed this out, and it is only with all my extensive competitive testing that I am finally acknowledging this to be a problem. I do believe midrange/reanimator is not the best way to build Daretti, as he himself does not provide true card advantage with either his +2 or his -2 abilities. As such, I think stax is still our best bet, but this does mean we're going to have to change the way we're building. I will be posting the updated decklist momentarily.

I didn't notice it before, but Clock of Omens might be a better choice than Unwinding Clock. My experience has been that there are certain activated abilities that you want to spam as much as possible (artifacts that tap for 3+ mana, The Chain Veil, etc), but you end up with plenty of artifacts that don't do anything with Unwinding Clock. It also shuts off Static Orb and Winter Orb during an opponent's end step.

To break down Paradox Engine's utility in this deck, here's the list of cards that it aids:

Mana rocks (1-mana only): Mox Diamond, Mox Opal.

Mana rocks (2+ mana): Mana Crypt, Sol Ring, Hedron Archive, Grim Monolith, Mana Vault, Basalt Monolith, Thran Dynamo, Metalworker.

Activated abilities: Goblin Charbelcher, The Chain Veil, Prototype Portal, Goblin Welder, Voltaic Key (doesn't work without other listed cards), Sensei's Divining Top (with spells at instant speed).

Based on this list, it looks like Paradox Engine will probably produce a lot of mana, but you aren't going to abuse activated abilities consistently and you don't have enough ways to draw cards to necessarily take advantage of all that mana. If you get Metalworker, Goblin Welder, or The Chain Veil+Mana Vault/Grim Monolith/Basalt Monolith/Thran Dynamo, you'll probably go nuts, but untapping Goblin Charbelcher and Mana Crypt a couple times per turn seems kind of weak for a 3-card combo. It's probably worth testing, but I think you'd want to add Staff of Domination and a couple other payoffs (which I don't think is the best direction for the deck).
