If the copied creature has in its mana cost, X is 0.

Any enters-the-battlefield abilities of the copied creature will trigger when Visage Bandit enters the battlefield. Any “as [this creature] enters the battlefield” or “[this creature] enters the battlefield with” abilities of the copied creature will also work.

If a plotted card has in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

Except for the listed exceptions, Visage Bandit copies exactly what was printed on the original creature and nothing else (unless that creature is copying something else or is a token; see below). It doesn’t copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

If the copied creature is copying something else, then Visage Bandit enters the battlefield as whatever that creature copied, with the stated exceptions.

You can choose not to copy anything. In that case, Visage Bandit simply enters the battlefield as a 2/2 Shapeshifter Rogue creature.

Plot abilities are written “Plot [cost],” which means “Any time you have priority during your main phase while the stack is empty, you may pay [cost] and exile this card from your hand. It becomes plotted.”

Exiling a card using its plot ability is a special action. Once you announce you’re taking that action, no other player can respond by trying to remove that card from your hand.

If the copied creature is a token, Visage Bandit copies the original characteristics of that token as stated by the effect that created that token, with the stated exceptions.

If you’re casting a plotted card from exile without paying its mana cost, you can’t choose to cast it for any other alternative costs. You can, however, pay additional costs, such as kicker costs. If the plotted card has any mandatory additional costs, those must still be paid to cast the spell.

You can’t cast a plotted card on the same turn it became plotted. On any future turn, you may cast that card from exile without paying its mana cost during your main phase while the stack is empty.

If Visage Bandit somehow enters the battlefield at the same time as another creature, Visage Bandit can’t become a copy of that creature. You may choose only a creature that’s already on the battlefield.
