Perhaps they'll touch back on old plot points. Remember how in the story of Eldritch Moon where everyone's minds were unraveling a bit and their darkest fears were being revealed? Maybe Gideon's biggest fear is his enjoyment of danger, as if he RELISHES the chance to be destructive. The fear that he may enjoy letting go of his morality an giving into to more destructive tendencies. Think Chandra but in a White planeswalker form. Maybe he'll have an effect like "+x: Sacrifice X amount of creatures, Gideon gains +X/+X and indestructible until the end of your opponent's next turn". That'd be pretty sick and could actually give a better overlay for people who may have always wanted to play him in a cohesive W/B kind of deck.
As for Liliana it may be more defensive since she is on someone else's planet hunting a demon that may have actually teamed up with bolas. That could be a little problematic for her. But...if you look closely at the background of her picture, you can see zombies rising which may be an indicator as to what one of her abilities may entail as far as her card effect goes. Maybe something like "+2: target player loses two life and discards a card. If the discarded card was a creature summon one 2/2 zombie token to your side of the field". That would be sort of like Ob Nixilis but instead of out rightly hurting yourself it can be used in a control like manner. Just throwing some ideas out there.
The art styles for the lands are very nice, despite the horns. Each one really entails how well this set is going into the Egyptianess of the set and just the way they were designed, shaded and colored really gives it an authentic feel to the set. I'm eager to see what new creatures this set holds. I foresee Zombie hordes in the future (or maybe some new mechanic like "Minion" or "MASTERING"). Those Egyptians were big on their servants, even if they are undead.
Also @ Jabilac and @Mnemosyne, it's good to be back, feel free to PM whenever you wish.
I'll be sure to PM you G.Moto just got to find some time, haha. Good to have you back in action, so to speak.
Liliana was planning to use the Gatewatch to
defeat her demons, but she is indentured to
Nicol Bolas. No doubt she thinks he can be killed like her demons in order to prevent being beholden to anyone. She underestimates him, but not as much as the rest of them, surprisingly including Jace.
I think
Nicol Bolas will force Liliana to obey him, either by revealing their plans to him or by indirectly betraying the Gatewatch. Using the
demon on his plane as leverage of sorts, shielding him from them, unless she co-operates.
Nicol Bolas could, as you mentioned, G.Moto, control Gideon by using his mental domination, to expose his fears and emotions to cause him to betray the Gatewatch. (He is a master at manipulation after all)
Nicol Bolas has played the Gatewatch like chess pieces, the entire time since Ravnica, even instigating the
release of the Eldrazi on Zendikar by luring Chandra there.
Jabilac, I want to know who the Raven man is as well, it is written like we should know who it is. (He's from Dominaria) I've heard people say it could be
Urza, but I highly doubt that. I think it could very well be Yawgmoth, since he was presumed
dead, his corpse is now tainting
Urborg, perhaps a portion of him has seeped into Liliana's consciousness, thus allowing him to live on through her. (He was known as Thran's healer, the original, heretical healer, giving Liliana the recipe for her brother's reanimation and triggering her planeswalker spark is more than feasible.)
