It's pretty good for Commander

This card works passively too: If you mill five cards and three are lands, youll put them all onto the battlefield

On the other hand Cryptic Command is in one colour and has a far far broader range on its abilities allowing you to be completely safe in almost any situation

Thus a card that dominated the formats it was legal in or has regular play in Modern or Legacy like Atarka's Command, Wild Cantor, Burning-Tree Emissary, Huntmaster of the Fells, Manamorphose, or Bloodbraid Elf, would still need to prove it's chops at the kitchen table

While it might seem like an unusual counter to ramping strategies, its a card that can be used strategically, even beyond its ramping ability
