Notes and Rules Information for 一往一来 // マイコイドの迷路:
- Only the English version of a Magic card receives Oracle updates and errata. View this card in English. (Scryfall note)
- If you control two copies of Twists and Turns and a creature you control would explore, instead you scry 1, then scry 1 again, then that creature explores. If you control three copies of Twists and Turns, you'd scry 1 an additional time before that creature explores, and so on. (2023-11-10)
- If an ability instructs a creature to explore, its controller reveals the top card of their library. If it's a land card, they'll put it into their hand. Otherwise, they'll put a +1/+1 counter on that creature, then choose to either leave that card on top of their library or put it into their graveyard. (2023-11-10)
- 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. (2023-11-10)
- If no card is revealed, most likely because that player's library is empty, the exploring creature receives a +1/+1 counter. (2023-11-10)
- If a resolving spell or ability instructs a specific creature to explore but that creature has left the battlefield, the creature still explores. If you reveal a nonland card this way, you won't put a +1/+1 counter on anything, but you may put the revealed card into your graveyard. Effects that trigger "whenever a creature explores" trigger as appropriate. (2023-11-10)
- 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. (2023-11-10)
- 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.) (2023-11-10)
