While Wizards of the Coast could have given the card new artwork that was less offensive, they opted to ban it instead
You can play it in decks that want lands in their hand for discard fodder, like Borborygmos Enraged
Craterhoof Behemoth A Triumph of the Hordes style effect, this card does what green does best: make creature big and make creature smash
Many Commander decks are multicoloured and synergistic, so its easy to convert them into a strong, recognisable draft archetype
But unless your deck is already geared toward other strategies that also take advantage of these cards, trying to refill a spent Iceberg is gimmicky at best, and an inefficient use of mana at worst
Having a card milled into your graveyard doesnt matter until its the last card in your library
