Both cards work exactly like a panic works with the difference being that they can be used against players of any range.
Unless there is a rule change in a different rule book that changes the way the draw a card symbol works it will be the same in the base game as it is in the expansions.
One thing that should be remembered is that these rules where all written in Italian and there are many issues with translations that lead to confusion in the rules. Not to mention there are many rules that are not fully clarified for new abilities in future expansions and how they interact with existing ones.
If you look at a panic card you will notice it has two symbols on it.
Rules
Draw a Card:1
Draw a card. If “any player”
is specified (see that symbol),
then you can draw a random
card from his hand, or you can
choose one in play in front of him.
If no player is specified, draw the top
card of the deck. In any case, c
Range One:
It specifies that the effect applies
to any one player at a distance
of the number or less. Note:
Mustang and Scope can alter this
distance, but weapons in play do not
Panic card:
The symbols state: “Draw
a card” from “a player at
distance 1”. Remember that this distance is not modified by
weapons, but only by cards such as Mustang and/or Scope.
Now if you look at conestoga card you will notice it has the same draw symbol but a different range symbol
Any Player:
It specifies that you can apply
the effect to any chosen player,
regardless of the distance.
The ragtime has an additional symbol that means you must discard an additional card to play it but otherwise operates the same.
