Hound of Tindalos

Should read: “Attach Hound of
Tindalos to a character (counts as an
Attachment support card)…”

If I use Hound of Tindalos’s (Core F110)
triggered effect to attach it to a character (which
makes it into an Attachment siupport card),
and it is destroyed, does it count as a character
or support card leaving play?
The Hound of Tindalos will count as a
support card leaving play. However, it
will revert to a character once it is in the
discard pile.

(1.11) Multiple Lasting Effects
Even if not triggered at the same time,
multiple lasting effects may affect the
same card at the same time. The order
in which the lasting effects take place
is irrelevant – the net sum result of all
lasting effects is applied to the card.
For example, a Young Deep One (Core
Set F52) (with 0 skill) is affected by
two Clover Club Bouncers(Core Set F65),
lowering that character’s skill by 2.
The Young Deep One’s controller then
attaches Notebook Sketches (Mountains
of Madness F4) to it, increasing the
Young Deep One’s skill by 1. The net sum
of these three lasting effects is that the
Young Deep One has a skill of -1.
Note, however, that a character’s skill is
never considered to be below zero for
purposes of resolving effects. Thus in
the example above, the Young Deep One’s
skill would count as though it were zero.
However, if another lasting effect would
give the Deep One +1 skill, the net skill
would remain at zero.
Lasting effects that affect other
character attributes (such as icons) work
in the same fashion.

So I was looking through the FAQ, hoping that it would address a question I have on this card, but couldn't find anything. My question is, if I am the person who plays Hound and I attach it to my opponents character. Am I still the controller, and therefore the only one who can use the Pay 1 action? And once the Pay 1 is used, does Hound go back to being a character card under the control of the person who played it?

Yes, you still control to attachment/character and only you can pay to move it.

What is the verdict on this card?

A couple of questions:

If Hound of Tindalos is exhausted, can it still use its action to attach to a character card?

When the Action to unattach is paid for, how does the Hound of Tindalos come back into play under its owners control, unexhausted or exhausted?

Yes, you can use its Action while its exhausted. Being exhausted only usually stops effects that have exhaust explicitly as part of a cost to trigger.

The Hounds become a support card when attached, but support cards can be in an exhausted state, and nothing says to change that, so the card would be exhausted when attached. And unless something like a refresh phase had caused it to become ready, it would return to being an exhausted character if you trigger the second power.

Btw, something a lot of opponents miss is that you can still use the first power to move the Hounds around, even when its attached, ie you don't have to turn it back into a character first.
