Vesuvan Drifter

2023-05-12 Any non-copy effect that began to apply to Vesuvan Drifter before it became a copy of a creature card will continue to apply to it after it becomes a copy. Auras and Equipment attached to Vesuvan Drifter will continue to work, as well as counters that change its power and toughness.

2023-05-12 If the top card of your library changes while you're casting a spell, playing a land, or activating an ability, you can't look at the new top card until you finish doing so. This means that if you cast the top card of your library, you can't look at the next one until you're done paying for that spell.

2023-05-12 Notably, while Vesuvan Drifter is a copy of another card, it doesn't have its own abilities. You won't be able to look at the top card of your library unless another effect allows you to do so.

2023-05-12 Vesuvan Drifter copies exactly what was printed on the original creature card and nothing else, except it has flying.

2023-05-12 Vesuvan Drifter lets you look at the top card of your library whenever you want (with one restriction—see below), even if you don't have priority. This action doesn't use the stack. Knowing what that card is becomes part of the information you have access to, just like you can look at the cards in your hand.
