Since i am most interested in martell been hearing alot about Ghaston Grey, however, it seems not that great to me. First not that many nobles so hard to draw when needed, also seems very spendy and although can bounce their key guys how can you afford to keep bouncing charactors while building your own charactors while spending gold to return them right after?

First, nothing stops you from using your knelt characters to return their standing/participating character to their hand. Second, if their character has any attachements, they are discarded. Third, you can then attack in intrigue (or Red Vengeance their intrigue challenge - or both). This is how you take advantage of it. It also adds to icon stripping and Parting Blow to deny your opponent challenges.

The printed version was completely insane because it didn't require that their character have printed cost equal to or lower than the Martell noble.

Combine with cost 2 mycella noble lead to terrible things.

It can be decent. But, you also have to fork over your own gold, just to return one of your own characters to your hand also. The resources are better spent in other ways, in my opinion.

In current errata yes, its power has been limited arguably to the point it might not be considered viable by some, but before, with Myrcella it was far to big a swing to send 4+ gold characters back to hand for a 2 gold character of your own.

Opponent has Beric? Bounce him.

Opponent has a character with several attachments? Bounce him.

Opponent stole your character with Reek , Enslaved, Seductive Promises? Bounce him.

Opponent has a Robert with 6 power on him? Bounce him.

Opponent's "Catelyn" is preventing you from declaring intrigue challenges? Bounce her.

Going to play a Valar next turn? Bounce your own character to dodge valar and let him have a bad character back.

Even at the very least "efficient" use, you're controlling challenges, and typically you can bounce a knelt character of cost X to bounce standing character of cost X (even trade by cost, but you at least got a challenge out of your character).

Ghaston Grey is still an excellent card. It's re-usable control and it's versatile.

Yes, I would say that against Beric is big, and would this be usuable against maeters then with chains guess be useful. I do see why it is good card just seems like really limits yourself too. And in order to bounce those better charactors would need to use either Doran or Red Viper so even more spendy for yourself. Just to me rather use venoumous blade to kill weaker charactors that mrycella would bounce, or get rid of icons on stronger charactors and use poison spear to kill the stronger guys (although bouncing Beric is big)

You can build your deck around making its effect more efficient for you. For example, using it out of house in an Alliance agenda deck with Norvos will make it significantly more efficient to play the expensive Lord Nobles. Some of the best characters are 3 gold, so Edric Dayne and Dagos Manwoody will help bounce them. Even using it with Myrcella Lannister helps you with challenge control against smaller characters. You can also use it to protect your nobles from kill effects, like Deadly etc.

It's a versatile card that is not an auto-include anymore and now has to be used in a more strategic deck building manner than it used to.

Just its existence on the table changes how your opponent must approach his challenges against you. If you have GG and a few nobles out, he knows realistically that if he wants to guarantee success in the challenge, he must over commit in case you choose to bounce guys. It is a very powerful card that drastically affects the challenges phase whether you choose to invoke it or not.

Effectively, because you can plan your resource curve accordingly, GG's drawback of being "spendy" is not a problem if the deck is built to take advantage of it.

The folks in the Deck Construction area would probably have more insight into how to build to minimize the "drawbacks" of the card.

So do most people that use GG build their deck around it then?

Yes. As you point out using Ghaston Grey is expensive. But if you plan for your deck to over come that expense, then it can be well worth it. Basically its not just a card you can toss in a Martell deck and expect to get great value out of it.

Playing GG without building the proper support for the Nobles and/or cost curve would be like putting Westeros Bleeds into your deck, but only having 3 Summer Seas and a Doran's Chambers in your deck for influence (so you need those 4 exact cards in play before you can use the event). It's an intrinsically useful card - that will almost never do you any good in that deck build.

Well Thank You guys for all the responses (: just getting excited for words (although going to get destroyed lol) just trying to learn as much can (:

one of my favorite uses for it is to bounce their bad characters and force them to kill a critical character to mil claim
