Another way to break the symmetry of Boom/Bust is by playing fetchlands. You target the fetch with Boom, then crack in response, fizzling that half of it while still destroying your opponent's land.

Funkydiscogod,

I think that Grindclock is an excellent option for this deck - that's a new card for me, thanks for suggesting it.

For me Thoughts of Ruin is one of those cards that can seem better than it is at first glance. Honestly, it seems like a superb way to catch up if your deck is failing early, but its usefulness takes place in such a narrow window (basically turn 3-5), I'm not sure that it has value in this deck.

hungry000,

That's a very good point, the problem is that there are only so many sources of colorless mana you can run in this deck and I think that Darksteel Citadel suits Boom/bust better if you have to choose between the two. If I were running Ponza, that would be a different story of course.

Speaking of Ponza, the land destruction deck that I've been having the most success with of late might technically be 'Ponza', but its really green with a splash of red. Definitely recommend that you check it out as its just a few Blood Moon's away from being Budget as well.

StoryArcher,
A few thoughts ...

• If you're going non-budget, you might consider running Snow-Covered Mountains instead. Folks will likely misplay against you, thinking you're on Skred or Dragon Skred. Plus, you could run Scrying Sheets.
• I only goldfished the deck a couple times but you might consider adding 2-3x Lands. With an average CMC (as I type this) of 2.62, 24 is optimal (source: the table at the bottom of this article by Hall of Famer Frank Karsten). And sure you've got the SSGs, but mana dorks only count for around 1/2 of a Land, and the SSGs don't stick around. So maybe 1/4-1/3 of a Land each? But you're also running Boom // Bust, which will often (though of course, not always) set you back one.

Some meta considerations ...

• Seems like Combo (e.g., Storm, KCI) would be very tough, since the deck is super-grindy and they don't need many Lands to go off. If it becomes a problem, maybe some Damping Sphere?
• Graveyard decks (e.g., Bridgevine, Dredge) could be very tough as well, since the deck throws a bunch of the opponent's cards in the 'yard. If that's an issue, maybe some Grafdigger's Cage, to go along with the Relics?
• Infect seems like it's be brutal. Maybe some Sudden Shock, if that becomes a problem.

Another option to consider is running this as RW. As hungry000 mentioned, some Arid Mesa would make Boom // Bust better. Plus you'd have access to Rest in Peace and other powerful White sideboard cards ...

Good luck (and good skill) with the deck!

I don't really understand what you mean by too many colorless mana sources. Fetchlands don't produce colorless mana. You can easily play 4-8 fetches without affecting the consistency of your manabase, and with only 4 Citadel, there's a much higher probability of Boom being a dead card in your hand without them. There just aren't any real downsides to playing a few fetches.

you put Millstone in your discription but it isnt in your deck.

mitzy, The deck originally featured Millstone but based on the advice offered above, I'm trying it out with Grindclock instead for a while.

Urza's Saga and maybe some cascade cards could help you find your combo pieces easier. For example, Bloodbraid Elf seems like a decent "finisher" choice over your dragon, since it can find pretty much any card in the deck (furthering your strategy), while also adding a clock.
