At the beginning of combat on your turn, this creature explores. Then you may have it become a copy of another creature you control until end of turn. (To have this creature
exploreCertain spells and abilities instruct a permanent to explore. To do so, that permanent’s controller reveals the top card of their library. If a land card is revealed this way, that player puts that card into their hand. Otherwise, that player puts a +1/+1 counter on the exploring permanent and may put the revealed card into their graveyard.
A permanent “explores” after the process described in rule 701.44a is complete, even if some or all of those actions were impossible.
If a permanent is no longer on the battlefield as an effect instructs it to explore, its last known information is used to determine which object explored and who controlled it.
If multiple permanents are instructed to explore at the same time, the first player in APNAP order who controls (or, in the case of a permanent no longer on the battlefield, last controlled; see rule 701.44c) one or more of those permanents chooses one of them and it explores. Then this process is repeated for each remaining instruction to explore. (CR 701.44),
revealTo reveal a card, show that card to all players for a brief time. If an effect causes a card to be revealed, it remains revealed for as long as necessary to complete the parts of the effect that card is relevant to. If the cost to cast a spell or activate an ability includes revealing a card, or if a card is revealed because an ability is activated from a hidden zone (see rule 602.2a), the card remains revealed from the time the spell or ability is announced until the time it leaves the stack. If revealing a card causes a triggered ability to trigger, the card remains revealed until that triggered ability leaves the stack. If that ability isn’t put onto the stack the next time a player would receive priority, the card ceases to be revealed.
Revealing a card doesn’t cause it to leave the zone it’s in.
A card that is currently revealed may be revealed again.
If cards in a player’s library are shuffled or otherwise reordered, any revealed cards that are reordered stop being revealed and become new objects.
Some effects instruct a player to look at one or more cards. Looking at a card follows the same rules as revealing a card, except that the card is shown only to the specified player. (CR 701.20) the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1
counterTo counter a spell or ability is to cancel it: remove it from the stack without resolving it. A counter on an object or player is instead a marker that changes characteristics or interacts with rules or abilities; for example, a +1/+1 counter modifies a creature’s power and toughness. (CR 701.6; 122.1) on this creature, then put the card back or put it into your graveyard.)
