Right, 5 mana for a 2/2 is slow, which is what I was thinking, but still the effect is really powerful. It only takes 2 more artifacts + 3 mana to produce 8 power and that's 8 power that can't be removed by a single plow. It triggers off of all artifacts, so sure you're often in top deck mode, but with roughly 70% of the deck as hits.
Artifact Creature — Assembly-Worker
Whenever you cast a historic spell, you may pay 1. If you do, create a token that's a copy of Mishra's Self-Replicator. (Artifacts, legendaries, and Sagas are historic.)
Since all artifacts are historic, this might have a home as a more resilient but slower precursor golem replacement in shops. The copies can also produce tokens, so if you play this followed by another artifact right away it is resilient to 1 STP since you'd still be able to make a token that can then continue copying. After 2-3 spells after this you'll have a crazy number of extra tokens. It's basically a big one sided genesis chamber that triggers off of all artifacts and makes more genesis chambers. It might be a bit too slow, but seems like a powerful engine for the long game in a grindy match.
@bobbyvictory Have you actually done the hypergeometric equations for the odds off those hands?
Your scenario of a workshop (1 of a 4 of), 2 inspectors (2 of a 4 of), 2 ravagers (2 of a 4 of), lotus sol ring or crypt (1 of a 3 of) overseer (1 of a 4 of) and ballista (1 of a 4 of) is really really rare. You might as well just complain about turn 1 Trinisphere because over the course of a large event I guarantee that leads to way more wins than that turn 2 play. I'm guessing if you actually did the math it would be comparable to the rarity of the other T2 wins.
I wonder how much budget prizes goes into to shifting the meta as well for champs. Champs is a pretty unique tournament as it is the largest sanctioned paper event each year. How many budget decks were in the room, maybe 15% of the event? And how many were playing null rod, most? This was part of the reason why I played shops at champs. With less spheres we can't really lock out decks that play the full set of moxen and other artifact mana, so all of the big blue/PO decks will likely be able to hurkyls into a win. Those matchups are actually pretty scary for the aggressive creature deck. Shops lists online often are playing 2-4 null rods because they are likely to face against PO. But when I know at champs there will naturally be more null rods, I can hedge and ignore PO and assume that if I make it to 3-0 without playing against it, that I've likely dodged a bad matchup for the day. With more null rods in the room, by the middle of the tournament the top tables shift to be more fair decks, or oath that isn't as reliant on fast mana. This is exactly what you want to see as a shops player (minus the oath) and is what you see when you look at the top 16, a lot of fair blue decks.
I'm not saying here that shops isn't the best deck. It clearly is based on mtgo results. I'm just suggesting that the unique meta of champs naturally having more null rod might have contributed to shops dominant performance rather than it just having a good performance. Shops is both the best deck in the format and was the best deck for the meta of champs, these two things combined always leads to dominance of the event, but not necessarily long term dominance.
@evouga That was exactly my point. Bobby was saying that it was ridiculous that shops could win on turn 2 when it assembled the rube goldberg machine, but really that's just vintage. Most decks should have some probably of a turn 2 win, or at least heavy control by turn 2. As for shops containing a deadly cocktail of disruption and pressure, the pressure has increased, but the disruption isn't nearly as good. This makes bombs like serenity, energy flux, by force, kataki or something like toxic deluge way more easy to cast. Its really hard for a shop deck to stop the opponent's plan nowadays, so it needs to be aggressive to have a chance, if you come with a good plan for shops you can win.
How about Land + Lotus + D rit + bargain? still more common (in terms of odds of having the cards in the opening 7) than the above line with shops and wins turn 1. The point here is not that a turn 2 win with shops isn't powerful, but that this is vintage and if you get the perfect set of cards to win on turn 2 1-2% of the time that should just be part of the format.
@rikter You're right, there needs to be more reporting of GRVs. I'm not sure there is a way to change player's attitudes though in regards to calling the judge for these little mistakes. A lot of players don't want to be that guy regardless of what it does to the game. That's why I think the only actual solution is to get the judges more actively involved in spotting GRVs. That is the only way we can guarantee more eyes are watching for GRVs in an event.
