Those familiar with the cards previewed so far will remember that one of the cards leaked on November 29 (and later confirmed on December 5) was called "Quicksmith Rebel." The similarity in names, converted mana costs, rarity, abilities, and creature types has not been lost on Magic: The Gathering players, with many postulating that there will either be a partial or full "Quicksmith" cycle of Human Artificers in Aether Revolt
The first is a triggered ability: "When this permanent enters the battlefield, target player may search their library for a card named [name], reveal it, put it into their hand, then shuffle." Note that the target player searches their library (which may be affected by effects such as that of Stranglehold) and that the card they find is revealed, even though these words aren't included in the ability's reminder text
Now, how much of that is due to the cards chosen, and how much is down to Lands being altogether less game-warping than say, Enchantments, is another question entirely
This is also the best card in this set for Type Four with infinite mana but just one spell per turn, so this is a first turn play there
