We can use this thread to discuss all the decks using the Greyjoy Faction ! (probably a lot of decks right now).
Currently, I have approx 40+ games with them on OCTGN. And they are my favorite faction in theme, style of play, and lore. I will be talking of course from my perspective on these games only because i'm new to the Got experience (not new to lcg, i come from netrunner).
First, I would like to say, Greyjoy is, if not first, one of the higher factions in terms of effectiveness. I would rate them tier 1 from the core experience.
-Lots of Stealth
-Good traits in general(Pillage, renown)
-Great 7 cost char
-Way to deal with enemy locations and attachments (We do not sow, Lordsport Shipwright)
-Great Sinergy between their cards (Stealth + effects when unopossed, ships and Drowned, etc)
- Few Intrigue Chars
Can't really think of any other particular weakness on this faction.
Asha is my favorite character right now. Running 3 of her is a must. Her ability allows you to stand her when she wins an unnoposed challenge, that means more challenges to win. Asha with little bird helps her get that third challenge, and saving her from tear of lys.
Euron is one of the best 7 cost in the game. Tricon with high strength. Renown and Pillage. Plus an ability that lets you take control of enemy locations. Getting an additional Kingsroad, or getting to use your own Casterly Rock is amazing, and a little sad for your opponent.
Balon is the main target for milk of the poppy in this faction. His ability lets you get so many unopposed challenges. You can even put Kraken to stealth those really strong Characters. Or use Throwing axe if a same strenght enemy wants to opposed you. Nobody opposes the Lord Reaper of Pyke !
You also get two more Stealth characters in this faction (Theon and Meister). A character with pillage to help Euron. You got Alannis for some annoying hand reduce effect and Aeron that helps you put characters in play from the dead pile (That's amazing btw).
The big location, Kraken, gives you card drawn and a help in power claim when you're close to the finish line. That alone would've been great. But if you have balon, he gets stealth. I would say 3 cost is actually not expensive at all.
Iron Fleet gives you more str, 2 if you are the first player (As Greyjoy you always want to be the first player). You can splash 3 of these in your deck, at 0 cost is never bad to draw these babies. Also, you want them in play for your drowned men.
Risen allows you to save a character and give him 1 more str. Is always great to have an unexpected save on hand. Also you can make balon almost unopossable by anyone. Zero cost btw.
Kraken Grasp on theory is pretty good. You can remove the str of a defending char on a challenge. However is a 5 str or lower char. I know that sounds pretty good, however in all my games i haven't used it at all. With balon and lots of stealth, you never seem to need it. Still an awesome event and is a zero cost too.
We do not sow is really a versatile event. You get to remove a Wall, or an annoying Plaza for just 1 gold. You get to remove milk from your characters. You get to choose a location that you can steal later with euron. 3 of these cards on your deck is the perfect amount.
I really believe Throwing Axe is an Overkill. Another help to get an unopposed challenge out of fear of getting your defending character killed. You almost never get to use it, but having it on a big character gets the effect you need.
I haven't tested everyone, so i would love to get feedback on these.
Stark: You get Arya, another stealth, and Sansa with an intrigue icon and a strong ability. However all the other military chars is not something you need. Also, just one usable event (just for starks). In my opinion the starks are not really a good banner house.
Tyrell: Good Banner. Margaery is Amazing in any faction. And left and right helps you with the defense. Also the events in this house are fun to play.
Lannister: All the green icons you need. Also cancels and remove characters that annoy.
Baratheon: My favorite banner so far. You get the melisandre team (Rhllor's), all have green icons btw, and get to kneel any char that stops you from getting those unopposed challenges. Also get another stealth with davos, who you can keep returning to your hand if you go all crazy on attack and don't want to def mil challenges.
Greyjoy: I Would say is pretty much who can get his table running the fastest. We have a pretty strong start so is all on the draw + plots.
Lannister: You really need to milk tyrion and get rid of cersei fast. They can ruin your hand if you don't get kraken early. Always remember about tear.
Targaryen: They have been my strongest enemy. They have a good set of icons among their chars. Daenerys messes up with balon str and burns are of course strong against any faction. Put to the sword from very early has been my only solution against them (Use it on dragons or whoever is on the table, they all so strong).
Nightwatch: Not a big deal, Berjen and ghost really troublesome for the stealth, however, most of their chars are really low on str, so balon is your main char in this matchup. Just keep them kneel with filthy accusations and make sure to get the wall kneeled every turn.
Martell: Viper with green challenges and Dorans game can't get really annoying. There is really no way to opposed that kind of play in late game, so you have to start strong and snowball from there. No need to fill table, just make sure to kill a lot of chars and don't let them fill theirs. We do not sow is a great tool in this matchup.
Tyrell: I didn't think left and right were good. But the fact that they dont have to kneel to defend makes them so strong against you. Also queen is probably going to win every int challenge so you need to get her out of the game fast. Growing strong will mess up your challenges, so you need to be aware of that every time.
Baratheon: The kneel is strong. I don't run any way to stand up my characters, so i guess that would be a counter play i should try. Robert is in my opinion the best 7 cost, however you can stealth him so put to the sword will be your friend here too. I think you have to really build a game plan on your deck for this matchup.
Stark: Easy so far. They can outrun you on military, however stealth is way too strong. If we are talking both fealty, i don't see any problem on this match up.
Confiscation: You will get milked everytime.
Filthy Accusations: Kneel someone you can't stealth or a big guy you can't out Balon.
Head on Spikes: Please use it on any faction.
Marched to the wall: Very strong for me if i get a good early game. Helps you get control on the table and has a big initiative.
Sneak Attack: Amazing to get first player and if you have a good challenge you can't fail. (Easily a 5 claim Pow challenge with renowns, and kraken if you get unopposed).
Those are my favorite to use, the others depend on the kind of deck and banner i'm using.
Hope to hear what you think about the Lords of the sea !
