Target creature you control explores. (Reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on the creature, then put the card back or put it into your graveyard.)
You may play an additional land this turn.

wotc19 Jan 2018
Once an ability that causes a creature to explore begins to resolve, no player may take any other actions until it's done. Notably, opponents can't try to remove the exploring creature after you reveal a nonland card but before it receives a counter.
wotc19 Jan 2018
In some unusual cases, noncreature permanents may explore. For example, if the creature card returned by Defossilize is somehow not a creature once it's on the battlefield, it can still explore. You'll take all the same actions, and you may end up putting a +1/+1 counter on the permanent. (Note that some effects target a creature, and those effects would still require a legal target to have it explore.)
wotc19 Jan 2018
The effects of multiples of Enter the Unknown in the same turn are cumulative. They're also cumulative with other effects that let you play additional lands, such as the one from Wayward Swordtooth.
wotc19 Jan 2018
If no card is revealed, most likely because that player's library is empty, the exploring creature receives a +1/+1 counter.
wotc19 Jan 2018
Enter the Unknown's effect allows you to play an additional land during your main phase. Doing so follows the normal timing rules for playing lands.
wotc19 Jan 2018
Some spells or abilities might cause a creature to explore multiple times in a row. If you reveal a nonland card when a creature explores and leave it on top of your library, then the creature explores again immediately afterwards, you'll reveal the same card again.
