Yeah, I'd like to see TNN nixed because he's the most recent in a sequence of printed mistakes that is fast erasing an entire cluster of archetypes from competitive Legacy play.

First we have the rise of the Show and Tell archetype as the premier combo deck in Legacy, which is notoriously difficult to hate out with all of the different threats various strains of the deck can plop onto the play area. Remember, hatebears were starting to get pretty decent against Storm and Dredge...not perfect, but enough that the aggro/combo matchup would be some miserable 10/90 affair. And looking towards a (now irrelevant) future, hate for Storm and Dredge was likely to gain in power faster than the combo decks themselves; Wizards has quite the hate-boner for both archetypes and the fundamental mechanics that would strengthen them (free shit from the graveyard, fast mana, tutoring, draw-engines*) are unlikely to see power increases. Unlike the Stupid Fucking Fatties that enable Show and Tell decks. We'll probably see more as Wizards pushes the envelope.

Elves supplanting Dredge as the secondary combo threat is also a wee bit of a toughie for aggro to cope with as it's a combo deck that is much harder to hate by a lot of convention means (Thalia, Teeg, every piece of extremely pushed gravehate, etc) that can also adopt a ground and pound game that isn't a goofy gimmick like old SI lists siding in Tomb of Urami or some shit.

Second, Control got Terminus (and, to a lesser extent, Supreme Verdict), making those matchups no longer favorable. I don't have any actual data, but I'd venture a guess that the matchups against say...Miracles are not in favor of the aggro deck.

Now, you have TNN making one of the few matchups where aggro might have had a chance, namely Blue tempo, into a dicey affair. The jury's still out on this one, as TNN could be all hype or some Super Secret Tech™ could be dug up to prop aggro's numbers up. But it still points to growing problem in the Legacy ecosystem.

Namely that the metagame is becoming more rapidly centered around Blue shells and combo decks (or some overlap). This is exacerbating issues of accessibility as well as chewing up the diversity of viable decktypes/playstyles that was one of Legacy's biggest selling points. While no-one doubts the idea that Legacy can self-correct due to the vast cardpool replete with powerful answers, it's less clear whether or not the format comes out for the better after multiple periods of self-correction. The mechanism of self-correction is only so robust against shocks to the system, and Wizards has been dumping a ton of awful (and powerful) cards into the Legacy pool...how many more Delvers/Griselbrands/TNNs will it take to make the format so bad that uber-Spikes finally wake up and realize bans aren't necessarily a bad thing?


*That aren't also in the category "Stupid Fucking Fatties"
