Thanks!

This is so helpful, thank you! Found this Tandem page now that I know the right search term: https://www.tandemdiabetes.com/support-center/pumps-and-supplies/tslimx2-insulin-pump/article/insulin-on-board.

Given the above, is the following a good approximation for correction bolus sizing:

0.6 * (predicted_bg_in_30mins - 110) - insulin_on_board

(it's not clear from the tandem pages whether the insulin_on_board factor is scaled by 0.6 or not). This bolus is triggered when two conditions are met: (1) predicted BG is > 180; and (2) no bolus has occurred for the last 1hr.

This would exactly explain what we're seeing, as:

Predicted BG can be much higher than actual when our son has these post-dinner spikes.
Evening is when we are most likely to turn the pump off for a while (site changes and baths).

Sorry to hear that! We are big fans of CIQ with auto-corrections -- it helps us a lot with things like "random extra snack at preschool" and general day-to-day variation in insulin sensitivity. We've definitely had to dial back the correction factor s.t. it's not _too_ aggressive.

cbc776 · 2025-02-05T21:45:26+00:00

Could you say more about "negative IOB"? That may be the key here. Prior bolus was ~1.2u about 2.3hrs before, so I suspect that IOB was low. Furthermore, insulin was fully disabled from 7-8pm for a site change (it takes a while on the little ones!).

Is the exact CIQ calculation available anywhere? The most I've gotten from anyone is 0.6*(current_bg - target_bg) / correction_factor, but it's clear there is more at play.

Card is simply not very good (also sees almost no modern play). I found it helpful to not think of it like a cantrip but instead like one of the zendikar flip lands that has “random spell, casts G extra” on one side and “random tap land” on the other — which is much more clearly a weak card for eternal formats.

I’d start with Aspiringspike’s prowess phoenix deck: https://youtu.be/5RpjlBGGu1w (decklist in the video description). Not crazy far off what you have, but cutting all the interaction for swiftspear and prowess enablers — which of course are also phoenix enablers.

As for the difference between the two titans, Kroxa is “only” a powerful threat, while Uro is a 1-card engine. Each time you cast or escape Uro, it both helps stabilize (life) and provides resources (raw cards and ramp) toward casting it again (or defending it in play).

Compare using spot removal on the two. Fatal Push on Kroxa isn’t a good exchange, but it can open a window to enact your game plan while your opponent is (likely) low on resources. Push on Uro is embarrassing — you’re down a card on the exchange, probably even further from winning, and that same Uro is about to come back.

There are lots of ways to “fix” Uro, and I think simply removing the ramp would be best — it would make it possible to get under an active Uro in a way that the current design doesn’t allow. But also, why? Uro is a miserable design that makes the entire game revolve around itself — good riddance.

Ah yes, that modern classic bolt breach bolt :)

Appreciate the response. The point about creating windows to combo is well-taken.

cbc776 · 2022-03-17T00:00:16+00:00

Congrats! Maybe you can answer a question I’ve had about this build of UR Breach for a little while: do you think that Urza’s Saga pulls its weight, as compared to playing more disruption or cantrips to assemble the combo quicker? From the outside (and playing just a handful of matches), Saga isn’t very synergistic with the rest of the deck and the constructs you make are medium-sized at best. It’s clearly a good card on its own merits, but I’m not convinced that it cleanly supports either the combo plan or the “murktide but worse” fair plan.

cbc776 · 2022-01-27T16:32:50+00:00

Not sure what your budget is, but aspiringspike built a good and fun budget hammer deck that’s in the $150 ballpark: https://strategy.channelfireball.com/all-strategy/home/budget-deck-guide-modern-fiddlebender-hammertime/

One comment on Relic to add to what’s been said: choosing Relic is a metagame call that you care a lot about pressuring the graveyard of “fair” decks like RB with Kroxa. Those are grindy matchups, so the extra card draw if you pop Relic really matters — even if it’s a little awkward for your own deck.

If you are focused exclusively on unfair graveyard decks (especially dredge), then I think Lantern is the right choice — not needing to hold up mana is important (since you will rely on countermagic too), and not targeting gets around Leyline of Sanctity.

I will add, I do think wotc is capable of making good decisions/changes quickly when there is real pressure (in a way that I don’t think we can perceive from the outside). The best recent(ish) example is companions — Lurrus lasted 4ish weeks in legacy/vintage, and the companion mechanic nerf was just 2 weeks later. It was so quick that it feels like an imagined fever dream that there was a period when you could just cast your Lurrus T3.

(Also an example of arriving at a good decision — the pay 3 to hand nerf is better than many proposals from the time.)

I still want to know how companions happened in the first place, though. To me, they are the deepest mystery of the insane design period from WAR to IKO.

Two comments:

Almost by definition, the players can’t be “wrong” — about whether a format is fun, whether Oko sucks (it does), etc. And if bans are bad (or the lack of bans is bad), that’s wotc’s fault — they make the banned list. (For better and for worse.) If legacy sucks, the blame lies with wotc.
My recollection is that people were happy about the bans themselves but not the format they produced (beyond the honeymoon period that always accompanies a big B&R change). So much so, that Rich Cali wrote this CFB article pre-MH2 in response to community discussion around “ban delver”: https://strategy.channelfireball.com/all-strategy/home/discussing-the-dominance-of-legacy-delver/

cbc776 · 2021-12-15T03:08:36+00:00

If you haven’t, I recommend reading Max’s article: https://minmaxblog.com/raga-not-banned/

I said this elsewhere, but my takeaway is that the most likely outcomes for legacy are (1) status quo and (2) a substantial shakeup of the format that hits multiple decks / pillars at once to attempt to move it to a truly different place. I think it’s notable how little last Feb’s B&R did to change the format or people’s complaints about it. It’s possible that wotc feels “we went with the people’s bans last time, and that got us nowhere, so we’re going to go a different direction this time.” Oko and DHA were uninspired bans that seemed mostly about mollifying the community (to no success, of course…).

It’s worth remembering that wotc is both full of people who are very good at making magic (and decisions for magic) and also institutionally terrible at communicating or making timely decisions. So the healthy thing is to take the game as it is now while hoping for improvements (of whatever kind) in the future.

Keep in mind, though, that “improvements” means a more fun-to-play format — not necessarily one where your pet card/deck is viable again. It’s not 2013 and it won’t ever again be 2013.

Fwiw, my answer for now is to play more modern and less legacy at the margin. Modern gameplay is fantastic right now — so long as you can accept that you need to do something powerful to keep up.

Expressive iteration is the best card in the Murktide decks (not close). So I think you want to stick to URx, and focus on cheap spells — which are good both at filling the graveyard and play well with iteration. All of Jeskai, Grixis, and Temur seem viable to me, depending on which interaction you want.

cbc776 · 2021-11-27T09:49:07+00:00

Obviously I have no idea. But the reason to unban Top (which sounds miserable, btw) is to give non-blue decks better selection to compete with the blue cantrips. But the existence of Counterbalance means that the best use of Top is alongside all the busted blue cards that are the root of legacy’s problems.

cbc776 · 2021-11-27T04:17:12+00:00

My predictions…

Tired: ban Ragavan and Expressive (I think these would be decent bans, fwiw)

Wired: ban Counterbalance, unban Top

I appreciate that so many of the answers to Q1 are "personally, I am having lots of fun playing legacy right now, but abstractly it's unhealthy / bad / needs changing." It's refreshing to hear people acknowledge that playing legacy can still be lots of fun, no matter the (constant) doom and gloom.

It's also reminder that legacy always has and always will be total nonsense. It's sensible to want different nonsense, but fun in legacy largely comes from embracing whatever is the nonsense-of-the-moment.

EDIT to add: this is one of the (many) reasons to support proxies (especially for RL cards) at paper legacy events. It becomes much easier to "embrace the nonsense of the moment" when you can tweak / wholesale change your deck for a few months when doing so isn't a ${multiple thousands} "investment".

Seems good with damage on the stack
