General tazri supports a tribal ally strategy innately. Every bit of text on the card is supporting an ally tribal strategy. If you show a newer player general tazri that's what they'll think the card is about. You can build a general tazri deck taking full advantage of its abilities and not even think of including food chain combos.
Anje is not this way. Within seconds of reading anje's text almost every player is thinking "so I run every madness card that's legal as a redraw to good cards". That's what the card was clearly designed to do, and it ends up being miserable in practice.
It's like saying "you can just not run wheels in leovold" yeah but in practice everyone is running wheels in leovold. (I am not saying anje is banworthy)
Or to take it to a bigger extreme, you could not run wheels in a nekusar deck, but then why are you playing a nekusar deck?
Generals lead you to deck construction decisions by what they support, nekusar supports wheels, titania supports land sacrifices, karlov supports life gain triggers. Anje supports playing the equivalent of a 20 card deck. The deck anje was clearly built to be the commander of, is not fun or interesting in the slightest.
To put it another way, you don't just have to make the deck weaker, you have to go and deliberately exclude synergy with your general to make room for weaker cards with anje. That's not good design. It feels awful to do this.
Sure, I thought about being able to use her to cycle the deck, but tbh there's a few pretty limiting factors: for one thing, you need the mana to actually play her, none of which has madness, and thus you have a solid chance of bricking well before you hit the combo if you draw too many mana sources. Two, the combo itself is very easily disrupted and BR has weak tools to prevents its disruption, and also the combo being disrupted almost certainly means you lose the game.
In short, I think WGD is certainly the most likely build to be popular in cEDH circles, and anje is most likely of the 2019 commanders to see cEDH play (as I predicted when she was spoiled) but I don't actually think the build is very good except for a surprise kill when people assume you're playing fair.
While cycling cards "for free" sounds great in theory, in practice it will usually lead to mana-flood because some amount of your deck has to be mana, and madness cards can't count towards those slots. And if Anje is countered or killed they are no longer free cycles. Unless you're on this go-for-broke combo plan, the risks don't seem worth the rewards to me.
Besides that, many players won't play that combo just because they don't find it interesting (myself included). Many niv players don't run curiosity for the same reason. Looking at EDHrec, the lowest inclusion madness cards I could find had a little less than 30% inclusion. Safe to say, then, than 70% of players are playing her "fair" i.e. they aren't just running every madness card to cycle their deck, but only the ones that might actually cast.
I think if you build the deck without WGD combo or some other combo, even if you do cycle madness cards without casting them a decent percentage of the time, you will still want to cast them at least occasionally. Is that an ideal play pattern for the madness tribal commander? Idk, it would have perhaps been better for her to incentivize casting rather than just discarding, but it's also kind of nice to get a real choice and not just mindless value, i.e. chulane. Sometimes you'll want to use her to cycle. Sometimes you'll want to use her for value.
It's also worth pointing out that Anje can work with madness is a more interesting and fair way by using mass reanimation, which is kind of cool and actually uses the madness cards, even if not by casting them.
General Tazri is terrible design! Sure, you could build an ally tribal deck, but the best build is food chain combo, so why would you do anything else? It's just a linear boring commander!
You've always got a choice in deck construction. No one is making you put in a combo. If you didn't have a combo to dig to, you'd probably be more inclined to actually cast your madness cards, because there's no magic bullet at the end of the rainbow. Granted, most madness cards aren't super strong, but when they don't cost a card and they all have flash, most of them are at least decent.
Unless you're playing cEDH, every deck has to intentionally limit its own power in some way. That's hardly unique to Anje.
