Ghost Town - Do abilities of the characters still count?
Yes he can use his ability.
For reference the Ghost Town card reads:

During their turns, eliminated players return to the game as ghosts.
They draw 3 cards  instead of 2, and cannot die. At the end of their
turn, they are eliminated again.

Note that it states that they are to draw cards, so the ghost's will enter at phase 1, the draw phase.
Clause &quot;The Saint&quot;'s special abillity is:

He draws one card more than the number of players, keeps 2 for
himself, then gives 1 to each player.

From the answer to Q14 on the FAQ for the High Noon from the publisher dV Giochi:

Q14. How many cards Bill Noface and Pixie Pete draw when they enter in play as ghosts  thanks to the Ghost
Town?
A. Bill Noface enters in play with 5 cards, Pixie Pete with 3 cards.

We can see that a players special ability does not suffer from the Ghost Town card being put into play.
However as Claus &quot;The Saint&quot; is not specified in any FAQ that I could find, we do not know if he should have gotten the advantage that the Ghost Town card gives (&quot;adding an extra card to the ghost&quot;, and thus giving him 6 cards to draw. So that he would end up with 3 cards for himself.), but seeing that Pixie Pete starts with 3 cards and not 4 (His special ability +1 (for the &quot;extra card&quot; from the Ghost Town), we have to assume that Claus &quot;The Saint&quot; get neither benefits or drawbacks from the the Ghost Town card.
