This deck might be a couple of elite two-drops away from being tier 1Strangleroot Geist is missed herebut dropping Xenagos should be one of the most powerful things youll be able to do in Standard for the next year and a half
So Warden great in a Landfall deck like this one, but easily fits into any White deck that runs a good amount of fetchlands, which the Warden synergizes particularly well with: playing and cracking a Flooded Strand gives you two landfall triggers to exile two cards, and you can even exile the Flooded Strand itself, putting it back into play once the Warden dies, which is a sweet (but convoluted) way to ramp in White
Im going to have to think about this for Standard but I can tell you that this is going to be a chase Commander card
Bonus: Shadows over Innistrad Tokens The problem with Arlinn Kord's Wolf token is that it's also produced by the Uncommon Pack Guardian, which means the supply will likely be higher than "Mythic only" tokens
Genuine cards will have a consistent and even finish
But Historic is a format that benefits from weird mechanics
