multimedia on Breya, "Brothers war? I Barely Know Her"

4 days ago

Hey, you left out highlighting or explaining the best infinite combo with Urza you have here. Urza + Myr Battlesphere + Ashnod's Altar = infinite Myrs, infinite colorless mana, infinite copies of all artifacts you control and infinite damage to each player with Breya.

Nice version so far on a semi budget, but build around the Urza + Battlesphere + Altar combo with more protection? Consider more combo protection? Urza + Battlesphere + Altar combo can be activated at instant speed at any time as long as you control all three permanents and have 6 colorless mana available. You're going to want more than 6 colorless mana if you intend to activate the combo though because you'll also want instant protection.

Darksteel Forge and Padeem, Consul of Innovation can protect Altar + Battlesphere, but they can't protect Urza without additional effect to make Urza an artifact. In the combo Urza is also not leaving the battlefield making him much easier to protect.


Assembling combos in Breya is made much easier with Wishclaw Talisman and because it's an artifact it has insane interaction with Breya. You can sac Wishclaw before opponent gains control of it, but still tutor for your card. When you activate Wishclaw it puts the entire effect as one trigger onto the stack. In response sac Wishclaw, putting it into your graveyard, then when you resolve Wishclaw trigger you tutor for your card, but opponent doesn't gain control of Wishclaw because it's no longer on the battlefield. Pair Wishclaw with Goblin Welder, Emry, Lurker of the Loch, Goblin Engineer or any other artifact recursion/reanimation source for a repeatable tutor.

Master Transmuter is powerful with high CMC artifacts especially when she can help assemble combos Darksteel Forge and Myr Battlesphere. It's also nice with Breya as a source to create more Thopters for 1 mana or to abuse any other artifact that has an ETB ability.


Consider more Pain lands and Artifact lands? They could replace some basic lands to improve color fixing/Breya interaction which can help gameplay. 23 basic lands is a lot in a four color deck.

Good luck with your deck.

multimedia on Breya Budget EDH

Hey, well done version on a budget.

If you like Thopters and want to make your deck more competitive then consider adding the budget Sword + Foundry combo? Sword of the Meek + Thopter Foundry creates Thopters equal to the amount of mana you have available. Foundry sacs Sword, moving Sword to graveyard, Foundry creates a 1/1 Thopter which then returns Sword to the battlefield attached to the Thopter and repeat. Even without Foundry, Sword is a good artifact with Breya for sac fodder because it can return to the battlefield.

If you add Ashnod's Altar to Sword of the Meek + Thopter Foundry then it's a combo to create infinite Thopters. Create infinite Thopters on an opponent's turn and then attack with them on your next turn to win or attack with them you're same turn with Thopter Engineer. Each time you sac a Thopter with Altar you make enough mana to activate Foundry twice. One Thopter is saced to make colorless mana and the other isn't, results in creating infinite Thopters and infinite colorless mana. Altar was just reprinted in the latest set Brothers War (BRO), Retro Artifacts version (BRR), it's down to $5.

Breya and her Thopters can be a wincon with Ashnod's Altar + Nim Deathmantle combo. Because Breya can sac herself to do 3 damage to a player then this can enable Deathmantle to repeatedly return her to the battlefield resulting in doing infinite damage to each opponent, 3 damage at a time. Altar sacs a Thopter + Breya which makes 4 mana and when Breya dies it triggers Deathmantle. Pay the 4 to return Breya to the battlefield and repeat. It's great for synergy that all these combo pieces are artifacts making it much easier to assemble them.


Wishclaw Talisman is busted with Breya because it's an artifact, she can sac it along with any other artifact before an opponent gains control of it. When you activate Wishclaw that puts the entire effect on the stack. In response to this, activate Breya and sac Wishclaw. When you resolve the Wishclaw trigger you search for your card, put it into your hand and since Wishclaw is no longer on the battlefield then an opponent doesn't gain control of it, it instead is in your graveyard to be recurred. Wishclaw is great with Emry, Lurker of the Loch and Goblin Welder for a repeatable tutor.

I see Unwinding Clock here which is good with Master Transmuter because it's an artifact and it taps for it's ability. Transmuter has a unique powerful effect because of the way it's worded, it doesn't target, you can return the same artifact you bounce to your hand right back to the battlefield. With Clock + Breya you can create two Thopters on each player's turn equal to the number of players. Transmuter is also great to cheat high CMC artifacts onto the battlefield by bouncing any artifact you control. Especially high CMC artifacts if they have an ETB ability such as Myr Battlesphere to keep creating Myrs, Spine of Ish Sah to keep destroying opponent permanents, Thought Monitor for repeatable draw, etc.


Making some land changes within your budget can make your deck more competitive by cutting some lands that always ETB tapped for lands that don't. The Pain lands and other lands like them are excellent budget lands especially when your Commander can gain life. They ETB untapped to make colorless mana or you take 1 damage to make a colored mana. The Pains have been reprinted in the last two Standard sets making them the least expensive right now. You can also start to find some Pain lands in new Commander precons which is a welcomed manabase upgrade.

Good luck with your deck.

wallisface on Yorions gone - what cards …

1 month ago

So, this is my current thinking for this list - basically moving Thalia to the sideboard, and trimming some cards i’d rather not see multiples of. Also ditching Ephemerate:

Land (23)

Creature (31)

Artifact (6)

Sideboard (15)

It looks like you might have a lot of trouble coming up with a blue source, when nearly half of your mana symbols are blue. Land bases are unfortunately expensive, but it looks like some of your dual-colored lands weren't that necessary. I copied your deck and experimented a bit: 1x Adarkar Wastes 4x Deserted Beach 3x Evolving Wilds 7x Island 3x Plains 4x Raffine's Tower 3x Tranquil Cove

You're needing 1x Adarkar Wastes and 3x Deserted Beach over what you've already got, which shouldn't be too rough on the wallet. Could potentially trade the Caves of Koilos 1:1 for the Wastes.

As far as counterspells go, as a cruel control player, I'll let most critters hit the field, then remove them at instant speed. I keep my counterspells for more dangerous things, like walkers or annoying creatures that have powerful ETB effects, or huge Enchantments.

I have replaced Scoured Barrens with Caves of Koilos, since having a dual land enter the battlefield untapped is more important than is gaining life, and the entire theme of this deck is gaining life, so the life loss from that land should not be a problem.

DemonDragonJ on Scoured Barrens or Tainted Field?

multimedia, you actually have a very good point, and Caves of Koilos was just reprinted, so its price should be low, although, if WotC ever prints enemy-colored versions of the "battle lands" (i.e., Canopy Vista, Cinder Glade, and so forth), I will unquestionably put the black/white land in this deck.

FartSeize, I need swamps to synergize with Castle Locthwain and plains to synergize with Emeria, The Sky Ruin.

Tainted Field enters the battlefield untapped for that reason it's a better land than Scoured Barrens. Caves of Koilos is better than both of them and Liesa gains life.
