Lapse of Certainty Discussion

enpc on Competitive Sunforger package

2 days ago

I currently run a Sunforger package in a 4 colour blood deck and have found Swords to Plowshares, Path to Exile and Chaos Warp to be enough value by themselves (there are a few red/green cards too but you can't run them).

Fire Covenant is also a good choice depending on your meta.

Secret tech though is Lapse of Certainty.

GoneWithLaw on Arahbo 1v1

I very much like your mana base, though I think it wouldn't be remiss of you to add a few more utility lands in the mix. In particular, Rogue's Passage can allow you to guarantee damage gets through, especially since you aren't running many sources of evasion. Blighted Woodland taps for mana and can ramp you later for the long game, while Hashep Oasis and Shefet Dunes are cheap and can pump your creatures.

Going back to evasion, your deck doesn't have a whole lot of it. Many Arahbo decks are running Rancor, but I feel too few of them are also running Gryff's Boon. It works surprisingly similar to Rancor, albeit it's a little bit more expensive. Still, given that it has built-in recursion means that you can consistently keep your cats in the air. If you end up adding more equipment, Prowler's Helm and Trailblazer's Boots practically guarantee your creatures will become unblockable.

If you want to stick to strictly creatures, on the more expensive side we have Pride of Lions that can damage your opponent regardless of trample/blockers. Very neat!

For 1v1, you can get a very quick kill in with Lost Leonin... with Infect plus Arahbo's eminence trigger, that's a 2 turn clock on one creature! The best part is that it curves very well with Ajani, Caller of the Pride for a turn 3 kill. If you'd like more ways to curve into a T3 kill in this deck with Lost Leonin, Duelist's Heritage and Silverblade Paladin both enable double strike for 3 mana.

The last bit of advice I have is in regards to cards in your deck like Thalia, Heretic Cathar. Personally, I think you should go big or go home on the stax types of effects. Just by themselves, they are mostly minor inconveniences. It is much more effective when you can combine Thalia with multiple effects that tap and lock down your opponent. At the very least, consider cards like Silence and Lapse of Certainty to throw your opponent off. Rule of Law for is fun option that also happens to have Leonin on it... flavor points!

I like many of your cards and others, not so much. Ill start with the good part.

Shivan Harvest: Awesome, gonna have to include that in my own deck. I keep forgetting this card exists.

Mardu Ascendancy: Yes and no. The first part of the enchantment is decent for an aggro deck, but the second part will be mostly useless. Your biggest enemy will be wraths, not combat. If you're running Edgar, you will probably have the most creatures.

Obzedat's Aid: A great card.

Lapse of Certainty: It always helps to be a little tricky. A spell like this will never go unused if you draw it during a game.

Bitterblossom: An excellent card for Edgar. I'd run it myself if I had one.

Now for the bad:

Quag Vampires: I would swap those guys with a

Shadow Alley Denizen, who gives more utility.

Vedalken Orrery: Why? You'll not generate a large amount of mana with this deck and your sorcery count is also low. Not worth the slot in this deck.

Ghostly Prison: You're gonna have a buttload of creatures, so it's just better to block with those, instead of a 3 cmc enchantment that you could replace with Vindicate, Shared Animosity, or a Boros Charm to protect yourself from wraths, which will make you cry. Also, you could fetch that last card with your sunforger, so there's that.No Stromkirk Captain? You just HAVE to run this guy, no way around that.

Ranger of Eos: Your one drops are not that impactful to warrant him being here.

Lastly, as suggestion, I would run Phyrexian Reclamation. You could return a vampire to your hand, cast it again, and activate Edgar's eminence in a recurring fashion.

Hope this helped!

Lapse of Certainty sounds hilarious to play against somebody's game ender. Cast that, and swing for lethal.

Painful Truths and Ancient Craving are more efficient than Damnable Pact.

Enlightened Tutor can find Sol Ring, Skullclamp, and both halves of the Exquisite Blood/Sanguine Bond combo.

Shared Triumph is a 2-mana anthem for vampires only. I think Adaptive Automaton is also very good.

I also think Teferi's Protection is a bad card. Like so bad that Lapse of Certainty might even be better, and that's a pretty bad card too.

Holonomic on Judgment Day: Avacyn the Purifier EDH | *PRIMER*

1 week ago

Hi there, just wanted to say thank you for taking the time to make this primer. I've only recently started playing MTG and found it really useful.Although I love the style the deck has I don't seem to be playing very well with it, I think it is due to most people seeing me as a threat and I always seem to get targeted rather quickly! (which isn't much of a problem as it makes it more fun)

I had a few thoughts about some alterations... I would really appreciate your feedback.

For sunforger mainly (see below), but also could be used to put essential equipment back into the deck to be tutored out again, the Tithe would increase chances of getting the Mistveil and could also be fetched with sunforger.Would the loss of the land be a problem here? Should I try and add 1 basic land back in or does the extra land tutor negate this?

Sunforger kit, with the above I thought I could add more targets for the sunforger. Here is a list of what I'm currently thinking.


  • Tithe - as mentioned above


  • Wild Ricochet - Works as a 'sort of' counterspell... sometimes works out better than one :))
  • Lapse of Certainty - Again, another counter - Could allow you (or other players) to plan for it to come up again... or just try and get the kill?
  • Dawn Charm - I put this in thinking it would counter a spell aimed at either me or a permanent I control... it does not. :) could still be useful though?

Damage Avoidance

  • Comeuppance - This card is so much fun...Counters some finishers such as Aetherflux Reservoir (or even kill them) It can also turn an all in attack of creatures into a board wipe :)
  • Faith's Reward - Could either be used after Avacyn flips or I think more importantly after a mass removal targetted at our artifacts.

From the above I decided to include the following, Tithe, Wild Ricochet, Comeuppance, Faith's Reward.Along with what you already have in your current list.

Do you think this is too much? Will this slow the tempo of the deck down too much? I think at the very least Comeuppance should be included. The Tithe only needs to be if you think Mistveil Plains is a good idea.

If the loss of land is ok, I still need to find 3 slots for the cards I am running. Any suggestions on what I should cut?

Thank you again!


Ps. I play only on MTGO... not sure if that changes things :)

Could work in the first game. But after that, it is way too easy to play around it - especially since we do not put any pressure on our opponent. If I were to take in some counters it would be Lapse of Certainty.

I think this deck needs a complete overhaul - probably by including black. That would give us access to hand disruption, which it sorely lacks.
