We also have the normal art for Immolating Glare.
Not much to say about Sphinx of the Final Word. It's a control deck finisher.
Oath of Nissa is a pretty unexpected effect. Even though it's restricted in card types and speed, it's surprising for green to get an effect that can be directly compared to Anticipate at one mana. Plus, even though it's a legendary enchantment, it is good in multiples because you can just use it as a sorcery effect. Also, as
the preview article points out, you could potentially play a mono-green deck with Tibalt if you really wanted to.
It's interesting how manlands work. Wandering Fumarole
feels weak, yet I can also tell that it will likely see Standard and perhaps even Modern play. Note that
LSV points out that if you switch the power and toughness and the opponent casts Lightning Bolt in response, there is absolutely nothing you can do with the land by itself to protect it.
If the stack looks like this (newest on top)
Bolt
Switch
Then there will be 3 damage on a 1/4 Fumarole, then it will switch to a 4/1 and die.
Switch
Bolt
Switch
Fumarole will become a 4/1, then it will be hit by a Lightning Bolt and die before it can switch again.
Switch
Switch
Bolt
Switch
This will be the first scenario again. Fumarole will become a 4/1 and then a 1/4 again. It will have 3 damage on it, then switch to a 4/1 and die.
EDIT: I now wonder if Oath of Gideon's static effect will be something like, "At the beginning of your upkeep, if you control Gideon, Jace, Chandra, and Nissa planeswalkers, then you win the game."
