Sideboard help for W/U Terminus

Modern Deck Help forum

Posted on Sept. 10, 2019, 2:26 p.m. by heckproof

Hey all,

I’ve been trying to decide for a while what to sideboard for in my W/U Terminus build, and I’ve got 14 of 15 cards locked down. But I still can’t decide what to put in my slot for Tron. I currently have Ceremonious Rejection in that slot, but Disdainful Stroke seems really decent as well. Here’s my thinking:

-CR is better in Affinity-filled metas. It also comes down faster and hits many Eldrazi.

-DS is good in more matchups, like Scapeshift or control mirrors.

My gut feeling is to replace Ceremonious Rejection with Disdainful Stroke , but I’m not sure. What do y’all think?

The list, if that helps: NOT A BREW

Mostly Ceremonious Rejection is better, it is great against Affinity, Tron, decent against Whirza, but honestly against the current metagame, running Sphinx seems bad, so does running Baneslayer and Timely. Idk, but I think you could run the both if you want, but I'd run neither. Personally I don't think it is a bad matchup.

Leyline of Sanctity needs to be like 4 slots tho, since burn if everywhere.

Thanks for the input! Yeah, I’m a huge fan of the Sphinx, but he is really narrow as far as versatility goes. He’s a nuclear megaton bomb in the mirror but does jack everywhere else. I’ll put in a Disdainful Stroke in his place, with the caveat that he comes back if it’s Stoneforge all day every day meta.

I’m also not really a super believer in Leyline of Sanctity because it feels like Burn jams in 4 Destructive Revelry in the side every time I put them in. I’d consider two though

I haven't played modern since KCI was a thing, but I used to run both in a fairly diverse meta. There's been times I've run both. There's been times I've run neither. I'd say I've been more happy with ceremonious over a long period of time.

There should be a UW discord floating around somewhere...

  • I personally am not a big fan of terminus builds, Pre-hoggakk i never used it and probably wont even with the format slowing down. -I do 24 lands (3 Celestals's 4 feild of ruin, flooded srand, 2x shock, 2x fast, 1x delta, 2 plains and the rest islands).
  • 4 paths and 1 oust. I filter with 4x opts (might drop for some Sv's) and 3 spell snares with a mana leak
  • 4x Snapcasters ( i dont do SFM)
  • a timely renforcesments ( it wins games) 3x force of negations.
  • I would recommend doing 2 narsets in MB with 2x 3feri. 2 jaces feels about right.

-Its important to play different sweepers to get around cards like meddling mage. People who played terminus from a study i found preformed worse the more copies they ran.

  • For SB i reccommend 2x surgicals, 1x veto, 2x distainful, 1x stoney silence (maybe more), 2x Celestial purge (consider cutting), 2x timely reinforcements, 2x monastery mentor, 1x lyra (or baneslayer or both), 2x engineered explosives.
  • 3x Commands beacuse vaule and its slower. Theya arent as good in faster times though. I do 1 wrath of god, and one supreme verdict.

  • I will say a few wall of omens feels really good, it helps absorb early damage like a goblin guide as well as draw a card.
  • Counter magic is important and which ones to run are really defendant one what you expect to run into so i recommend looking at those, as well as the SB recommendations i gave.
  • If you have other questions or comments I would be happy to hear them out.

Hey, thanks for the input. Yes, I know that Terminus probably isn’t the best choice given the meta. That being said, I still really enjoy the playstyle. I might switch over to the more super friends-ish deck of today, though.

A quick question, though: what are your thoughts on Teferi, Hero of Dominaria ? I realize that you probably don’t want more than one in a non-Jeskai build, but I still kinda want one in the main. Is he worth running in W/U?

  • The more planes walkers you run the worse off you are being they are late game. A lot of our package is getting to late game, and preventing our the other person from recovering. I'd Run maybe 1 or 2 at most. Id probably cut a jace for the 2nd one. I have played to much in the current meta but i do know most people arent running that many of them anymore.
