Quick takeaways:
Tinder Wall is a very good card. It's especially precious in situations where a Thalia hits play on turn two, which it gets around without the additional investment. Additionally, it helps power out a turn-one Ruby Medallion. The ability to do that offsets the (predominant) reason to play bad cards in the deck like Ancient Tomb and Crystal Vein, and to a lesser extent City of Traitors. Not only does it block extremely well, it does just what you want on the first turn without losing a land drop (Vein) or sustain damage with a colorless resource (Tomb) that doesn't produce red mana. Life is an underrated resource here, especially in variations that run Probe and Tomb. I just think Tinder Wall is the best option for what it does.
Main-deck Empty the Warrens is honestly very good. Being on the play and navigating to a situation where you can dump 8-12 Goblins on turn one just wins free games. If you flip it off Fury, it's even more disgusting. Leaning too heavily on Burning Wish is not something you want to do all the time, and while it takes up design space it also provides a strategic opportunity to win games.
I run Volcanic Islands to support Ponder and Probe, with Performance out of the board. This also can lead to misleading situations for an opponent who may see Volcanic into Ponder and assume something much different than Ruby Storm, which again leads to free wins and the potential for changed decision trees against skilled opponents. Regardless, Ponder is just amazing by itself and bolsters consistency to the deck. When powering out a Past in Flames, sometimes Ponder is all you need in the graveyard. I think it's vastly superior than Gamble in this deck, regardless of their respective utilities. Telemin Performance is also powerful win condition against Lands, Reanimator or Sneak and Show - hence its inclusion.
The Taigas are there to support Tinder Wall, Xantid Swarm and Hull Breach out of the board. I play three because there may be situations where Pulverize is used, and having access to another could be crucial.
I am a big fan of Apocalypse or other reset-buttons out of the board. In the event you desperately need to restart the game, this is the best option available at five mana. The deck operates with fast mana inherently, so being able to recoup isn't always going to be too hard to do. It's risky, no doubt, but if you're facing down lethal and you can access it, you'll be glad you have it. I would recommend only playing this in LED builds, because spiking fast mana like LED after playing it with a discarded Past in Flames in the graveyard could be key.
I like Pulverize, as well. This deck plays plenty of Mountains to support it's alternate cost - something TES wanted to do but couldn't because of the need for extra Mountains. Getting that added value against decks that pack Chalice, Trinisphere, etc. can be critical, and the card can just win games outright.
Reforge the Soul is in the sideboard to support a draw-seven effect if needed. One thing I really don't like is giving my opponent seven fresh cards, regardless of what they're playing. You'll note decks like TES and ANT moved away from cards like Diminishing Returns because they were able to abuse Ad Nauseam. It's always nice to draw cards, but this is a card that, regardless if Ruby Medallion is in play can be a risky play. I like it in concert with Empty the Warrens main, because you can invest the mana to draw cards and eventually bait into a follow-up two or three-mana Empty for X Goblins. Other than that, I know why it's in the deck but I have my reservations.
Blood Moon is a one-card combo.
This deck is very capable of firing off big Grapeshots with multiple Pasts, and sometimes it can be used to clear the board against decks like Elves, Death and Taxes, etc.
I teeter on adding Desperate Ritual into the deck. Dark Ritual is an incredibly powerful card, and Ruby Medallion transforms it into a red Dark Ritual flat. I've seen folks eschew it, and I'm beginning to wonder if it's actually just better in this particular deck because you really want to abuse Ruby Medallion. Some lists aren't running a lot of XR spells to abuse it, which in turn kind of weakens the argument for running Ruby Medallion anyhow. To really get power out of it, I'm wondering if playing some number of Desperate Ritual with Simian Spirit Guide is optimal, or Tinder Wall with Guide. Spirit Guide is just so good in a deck like this to perform so many tasks. I'm on the fence, but Tinder Wall is just a crazy-good card for one mana. It gives you the turn-one Ruby and lets you keep your land.
