Detailed notes
## Background Published on YouTube by TCGplayer on May 3, 2012, this video features professional player Luis Scott-Vargas sharing his commentary as he breaks Magic Online. The description highlights LSV exploring the game's limits alongside links to ChannelFireball content.
## TL;DR While navigating a Magic Online control mirror, Luis Scott-Vargas notices an unusual board state where his opponent chains three Oblivion Rings onto one another. Rather than taking a straightforward path to victory with Elesh Norn, Luis intentionally triggers an inescapable, mandatory trigger loop to test the software's engine. The endless interaction overwhelms the client, prompting a server desync recovery that fruitlessly replays the entire match at hyperspeed from turn one. Upon reaching the identical loop, the replay crashes the engine once again, ultimately forcing the system to scrap the corrupted match and begin a fresh game.
## Atmosphere & style The video radiates a lighthearted, mischievous charm fueled by Luis Scott-Vargas's signature dry humor and nonchalant delivery. Starting as a patient, methodical control mirror, the mood quickly pivots into playful curiosity as competitive optimization takes a backseat to scientific trolling. Watching the overwhelmed software fruitlessly reconstruct the game at breakneck speed, only to deterministically crash itself all over again, creates a uniquely hilarious spectacle of digital game mechanics collapsing in real time.

## Key takeaways - [00:00](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=0s) Nihil Spellbomb was deployed proactively to neutralize the value of the opponent's graveyard and Snapcaster Mage recursion. - [00:00](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=0s) LSV allowed a massive Blue Sun's Zenith to resolve to avoid trading Dissipate unfavorably into an anticipated Mana Leak. - [00:00](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=0s) Elesh Norn, Grand Cenobite was cast primarily as a must-answer clock designed to trade with opposing countermagic. - [00:00](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=0s) The game state inverted when the opponent cast three Oblivion Rings in sequence, exiling their own enchantments instead of applying pressure. - [01:40](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=100s) Under official Magic rules, a loop of mandatory triggers with no choices and no other legal targets results in an immediate draw. - [01:40](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=100s) Faced with an easy win versus exploring software edge cases, LSV intentionally triggered the infinite loop for entertainment value. - [01:40](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=100s) Once initiated, the three Oblivion Rings cycled through entering and leaving the battlefield indefinitely without requiring any player decisions. - [01:40](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=100s) Magic Online failed to identify the mandatory loop, causing the client engine to lock up while triggers continuously burned match time. - [03:04](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=184s) The software attempted an automatic recovery routine by rewinding to turn one and fast-forwarding through every player action at high speed. - [03:04](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=184s) The automated reconstruction deterministically repeated the fatal trigger sequence, locking the client in a recursive failure state. - [03:04](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=184s) After multiple failed replay cycles, the MTGO server terminated the game state and registered it as a loss for LSV to begin the next game.
## Detailed walkthrough ### [00:00](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=0s) Maneuvering the Control Mirror and the Three Oblivion Rings
Luis Scott-Vargas navigates a tense control mirror on Magic Online. Factoring in countermagic like Dissipate, he feels comfortable letting certain plays resolve since he has another Consecrated Sphinx in reserve. To limit the effectiveness of his opponent's Snapcaster Mage, Luis deploys a Nihil Spellbomb to keep the graveyard in check. He then decides to cast Elesh Norn, Grand Cenobite, noting that while she might not do an overwhelming amount immediately, she represents a legitimate clock that can close out the game, making him happy to trade her for an opposing counterspell. When the opponent casts a large Blue Sun's Zenith, Luis opts not to fight over it with Dissipate, realizing his opponent can easily back it up with Mana Leak.
The opponent draws eight cards, threatening potential haymakers like Karn Liberated. However, rather than slamming an insurmountable threat, the opponent begins casting Oblivion Rings. First, one Oblivion Ring targets Luis's permanent. Then, in a bizarre sequencing decision, the opponent casts a second Oblivion Ring targeting their own first Oblivion Ring, followed by a third Oblivion Ring to complete what Luis calls the "full trifecta." This bizarre chain drastically shifts the momentum in Luis's favor.
“This game went from looking pretty bad to looking much much better very quickly here,” Luis remarks, marveling that the turning point was merely the opponent choosing to Oblivion Ring their own card.
- **Nihil Spellbomb Utility:** Deployed primarily to diminish the value of the opponent's Snapcaster Mages by threatening instant-speed graveyard exile. - **Threat Assessment:** Luis allows Blue Sun's Zenith to resolve to avoid trading Dissipate directly into an open Mana Leak. - **Board State Shift:** The opponent exhausts three copies of Oblivion Ring in rapid succession, exiling their own enchantments rather than applying decisive pressure.
[01:40](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=100s) Triggering the Infinite Oblivion Ring Loop
Luis assesses his position, holding counterspells including Dissipate and Snapcaster Mage while threatening to win the game with Elesh Norn. He engages in a counter war over a subsequent spell, trading counters before noticing a peculiar vulnerability in the game state. With three Oblivion Rings on the battlefield exiling one another and no other legal nonland targets in play, removing or triggering the sequence properly could result in a mandatory, unending loop. In paper Magic, an inescapable loop of mandatory triggers with no choices draws the game. On Magic Online, however, it is notorious for crashing the server.
Faced with a clean route to victory versus the irresistible curiosity of testing software boundaries, Luis decides to trigger the loop. He acknowledges that the opponent could theoretically have an answer like Snapcaster Mage, but proceeds anyway. Once the trigger chain begins, the Oblivion Rings begin continuously exiling and returning each other without any player input required.
“I never claimed I wasn't very stupid, but this is just too funny to pass up,” Luis jokes as both players hit F6 to pass priority indefinitely while the game engine churns through triggers and bleeds the clock.

[03:04](https://www.youtube.com/watch?v=AGXG5rNe_tI&t=184s) Crashing MTGO and the Hyperspeed Replay
The Oblivion Ring triggers continue firing non-stop for several minutes, completely overwhelming the Magic Online client. Rather than terminating gracefully into a match draw, the game engine destabilizes. Suddenly, the client attempts an automatic server-side desync recovery: it resets the entire match back to turn one and begins replaying every action made by both players at hyper-accelerated speed.
Luis watches with amusement as lands tap, spells resolve in rapid fast-forward motion, Elesh Norn lands on the board, and the third Oblivion Ring hits the battlefield once again. Unsurprisingly, upon reaching the exact turn where the loop was initiated, the client re-enters the same infinite trigger sequence and stalls all over again. Luis cuts the video to spare the audience the repetitive waiting period. After the system attempts another fruitless replay loop, the software finally gives up on the corrupted state and forces a fresh game. Luis prepares for the next game, remarking with dry amusement that he gets to choose to play first because he technically lost game one.
“Yeah, that's the game. It restarted, and MODO's not sure what to do right now,” Luis observes as the automated replay engine hopelessly plays right back into the fatal crash turn.
- **Client Desync Behavior:** Instead of ending in a draw, Magic Online attempted to reconstruct the game state by replaying every individual game action from turn one at high speed. - **Loop Recursion:** The fast-forward reconstruction deterministically arrived back at the three-ring interaction, immediately triggering the exact same fatal crash state. - **Eventual Resolution:** After looping through multiple system retries, the server aborted the broken game instance and moved the players into the subsequent game.
