Leyline of Combustion Discussion

pistolpeteiii on Mardu's Angelic Enchantments - It Wins

I've seen a few lists running the combo, but I like your inclusion of for the removal options. With that being said, I have a few suggestions.

  • I think I'd like to lean into the Divine Visitation + Outlaws' Merriment plan a little more if I were building the deck, as it is your best way to win. Running 4 copies of the token producer and 3 for the enhancer would probably be best for consistency sake. Neither are legendary, so its not detrimental to your board state to draw more than 1 copy per game, however two Divine Visitation may be damaging since you have little to no card draw. To do this I would cut Leyline of Combustion as it doesn't really fit the control plan, and relies on you to have targets for removal. Also, going down a copy of Fires of Invention might be beneficial. You don't really have the card draw to make 2 important plays every turn, and again it kinda doesn't fit the control feel you have with the rest of the build.

  • I would consider Deafening Clarion for the build, as it is a way to both gain life back, or sweep the board when facing aggro decks. It fits the colors, and is less mana intensive than Kaya's Wrath .

  • Lastly, I think Murderous Rider should be a main-deck consideration. The life gain pairs well with Dawn of Hope , and provides versatile removal options along with a creature for 1 slot in the deck. Cutting the last two copies of Fires of Invention seems sensible to me for this addition, as the lack of card draw previously stated hinders the power level ceiling of that card.

I hope you like my suggestions, let me know if you'd like to know any more reasoning behind what I've selected!

I never considered Bag of Holding but will definetely test it! Also I ran into many lifegain decks lately with that hideous Cauldron Familiar + Witch's Oven or soul sister Ajani, Strength of the Pride Token Ability + Ajani's Welcome or Bishop of Wings . Ive thought about Leyline of Combustion in the sideboard against it.

Looks like a solid deck. Looks alot like my deck, Basic Boros Burn: Tier one version (the goal). But I have to ask, why a playset of Leyline of Combustion ? Its great if it's in your opening hand, but wont it be a dead card if it's not? Same with Leyline of Punishment . I think three copies of Skullcrack should replace it in your side board, with one copy of Rest in Peace . But I'm still a new player, and honestly Leyline of Combustion looks fun to play around with!

Greetings! I've got a brick of cards to sell!



I am doing this, not because I need the cash immediately, but because I really don't want to ship out a ton of packages and wait forever. I just want to unload so I can fund different hobbies :3

I have chat open and available to all :) Send me a message if you are interested!

Jkerb if Leyline of Combustion and Plague Engineer are working for you in your current meta, then keep using them. Everyone’s playgroups are different and so need to be tailored to what’s going on. I am going to eleborate a bit more below on why i think you should reconsider their practicality though.

Leyline of Combustion : breaking down deck archetypes into their typical 4 groups (aggro, combo, midrange, control), it appears this card is only going to be useful against 1 of these 4 archetypes.

Aggro (stompy, affinity, infect etc) generally have no spells to interact with your stuff at all, or if they do it’s too few to matter. Same goes for Combo (storm, druid, etc). Yes grapeshot does need to target you, but they’ll easily be able to bounce the enchantment before then via Gifts. Control is a trickier one, but in general will be able to continue countering stuff unimpeded, and have lots of global-effects that get around the damage.

The main threats this card deals with are Midrange and Burn. And that’s kindof it. And if that midrange deck is Deaths Shadow, they’ll probably love you playing this. It feels like around 2/3rds of the time, it’s going to be a dead card in hand.

Plague Engineer is only really worth a slot against tribal decks - so humans, spirits, elves, maybe hardened scales (construct). But again, there are far more decks that this card doesn’t apply to. Dredge runs loads of different creature types, and is unlikely to care whether they’re swinging for 24, or 20. Phoenix also can’t be easily pinned down due to running all different creature types (i.e even if you weaken the birds, there’s still a massive horror beating you down), as well as the new M20 enchant and winning that way. The Rock again uses all different types, and probably won’t care if any one of them is a little weaker (except for Bob).

Basically non-tribal creature decks won’t care. And then, obviously there’s still a massive % of the meta without creatures. Storm, Tron, etc just laugh at this.

But, as i said at the start - if it works in your local meta, keep using them. Just be weary that there seems like a lot of cases they’ll be redundant.

Thank you wallisface and JKRice for your thoughts/input on the deck, it has been extremely helpful. I've swapped around some cards based off the advice you gave but I'd still like to discuss a couple of the points you made.

Firstly, I still feel that the inclusion of 4 Leyline of Combustion s main deck is fine. As I said in the description, there are loads of cards that target both us and the permanents we control in Modern and Leyline will punish our opponents for all of them if not dealt with, thus helping to speed up the clock to our opponent's impending demise in the process. While it may not grant the same level of player protection as Leyline of Sanctity , it provides a soft one that covers not only us but our creatures, lands and enchantments as well and it can stack with itself to make the effect even more punishing. This way, any decks that try to kill us with targeting spells will hurt themselves severely in the process and might even flat out be unable to deal significant enough damage to warrant doing it. For example if they were to try and kill us by with lightning bolts, the 2 or possibly 4+ damage (if we have multiple Leylines in our starting hand) that they take before their 3 damage from lightning bolt resolves just isn't maintainable to keep taking. That damage dealt by Leyline is essentially just free damage to our opponents that they paid and used a card for and that in addition to what our deck is doing leads to rapid life loss in match ups like that. Additionally, if Leyline doesn't cut it, we can always swap it out for cards in our sideboard that would better fit the match up. However, I feel there are currently enough decks where it is good to keep it in the main. (Plus, it's fun to watch all discard cards become Thoughtseize s or worse in terms of damage, for Thoughtseize itself to become really damaging and to blink creatures before they get removed and having the opponent still take damage.)

As for Plague Engineer , it can be a seriously oppressive card. Against creature decks, there is generally a high number of one type (like zombies in dredge or phoenixs in Izzet Phoenix) and Plague Engineer makes it so that at the very least they are much less effective and otherwise just flat out kills them acting like a continual board wipe. There are so many lower toughness creatures in modern that should you get a couple Engineer out, they drop like flies. Plus, being able to change the chosen type with a simple blink makes it so you can react to whatever your opponents tries to pull. The Engineer also works with Mentor of the Meek and can be a nasty blocker for bigger creatures (especially when given protection). I can definitely see where it falls short in different circumstances (like against Thing in the Ice) but it can just gun down so many creatures in so many different match ups that I felt it was good. The match ups where the Engineer is bad tend to be the opposite of the ones where Leyline of Combustion is so when that is the case, we can then use the Engineer's spot to grab our sideboard cards.

The multiple 4 drops in the deck can be a problem for sure but so far in trying the deck through the simulation feature I've found that because the Leylines don't always have to be cast, it hasn't been too great a problem. Plus using Seasoned Pyromancer we can chew through the 4 drops we don't need to get to better options.

I agree that Lingering Souls (which works great with Seasoned Pyromancer ) would be a nice include but in trying to decide on what to cut for it, I have had some difficulties. The same goes for Thought-Knot Seer and Fiend Hunter .

Also, thank you both for the recommendations of Seasoned Pyromancer and Damping Sphere , I hadn't thought of including those for some reason. They were good choices for sure. I'm not very experienced in Modern land bases as well so the recommendation for cutting a couple was very much appreciated.

Nice deck! I have some suggestions

24 is kind of a high land count, and you don’t really see it in decks that aren’t ramp theme. I would recommend cutting out your two Shambling Vent s. For the nonlands, there are a couple of odd choices I see. Leyline of Combustion is just strictly bad. It would be better to have a less expensive creature that provides more value for the deck. Also, Plague Engineer seems like more of a sideboard card than anything else. Maybe have one or two of him in Mainboard, but three is a lot. Lastly, Eerie Interlude might seem like a good card, but you actually don’t have a lot of valuable etb creatures. Also, when you blink your blossom tokens, they don’t come back to the battlefield, as per the ruling in interlude. I think you don’t need four giver of runes, just three, and I also think you should have three angels and one felidar guardian, since angel has flash.

I would recommend more ETB creatures. Seasoned Pyromancer is the new card that I have seen in a lot of mardu decks, and it would be a crazy value generator, giving you tokens when you flicker it with your angel and deluded guardian as well as providing three etb triggers for purphoros and impact tremors. Thought-Knot Seer might be a good card, getting rid of any answers your opponent might have in their hand. Fiend Hunter could also be good; you can play fiend hunter, exiling one of their creatures, then in response to the trigger you flicker fiend hunter. The card is exiled, but it will never get the “when fiend hunter leaves the battlefield, trying to opponent’s battlefield” trigger, since the flickered fiend hunter is treated as an entirely new creature. If you want to just spam out creatures, Lingering Souls and Secure the Wastes could work quite well.
