Craterhoof Behemoth is a very powerful card. It's not difficult to build up a board full of little creatures and incidental tokens, and Craterhoof turns them into a legitimate win condition. There are other anthems that can be used to buff a team -
Overrun,
Pathbreaker Ibex,
Overwhelming Stampede,
Dragon Throne of Tarkir,
Beastmaster Ascension, etc. However, Craterhoof tends to scale to lethal much faster than other options.
However, I'd say that the primary reason why Craterhoof is so strong is actually because it's an ETB trigger. Very simply, most of the other big scaling effects can be stopped with spot removal - if you're counting on Pathbreaker Ibex or a massive
Omnath, Locus of Mana + Overwhelming Stampede to buff your team, those can be stopped by a single
Doom Blade, while Craterhoof usually can't be stopped without an actual
Fog. It's possible to play around Craterhoof a bit by utilizing frequent board wipes, but that isn't really feasible for every deck.... and, more critically, wiping a board of useless creatures and tokens juuuust in case of Craterhoof feels pretty bad.
Anyway, Craterhoof tends to induce groans, similar to
Cyclonic Rift. There are substitutes, but it's far and away the best instance of the effect, which results in it seeing a lot of play. It's almost somewhat impressive that it hasn't been power creeped since its original printing... but then again, that's probably for the best, since it's already sort of pushing the limits. I'll also note that as a creature, Craterhoof is also pretty easy for green decks to tutor up and recur, which certainly contributes to the problem. Craterhoof as a 1-of creature may be okay, but fetching it on demand with
Worldly Tutor /
Survival of the Fittest /
Tooth and Nail to end every game is going to stick in peoples' minds.
If you want this effect in other colors, I'll point to
Márton Stromgald and
Jazal Goldmane. That said, they are both significantly clunkier to use, and not granting trample makes it more difficult to guarantee a table kill.
...I would say that Craterhoof induces fewer groans than
Triumph of the Hordes, but it's certainly close.
