It's quite good, but it's also not broken
The Mill archetype has been held back in Commander by a couple big factors: the decks have more cards to mill from each opposing deck, and the games are rarely as long as youd like them to be
When it comes into play, it taps down all legendary creatures, and it keeps legends from 'readying' in the untap phase, potentially locking them down for the rest of the match
Remember that tapping for mana counts an activated ability here, so it doesnt only work as a three mana strip mine

"Mill" is a colloquial term that originates from the card Millstone, used here to mean "putting the top cards of a player's library into his or her graveyard." For example, you could say, "In the finals of the Pro Tour Qualifier, Herbert cast Tome Scour to mill away my final five cards, dashing my chances of playing on the Pro Tour." There are many players who will play with Tome Scour in their decks
