Man Kara has some heavy armor on, yet now she has decided to load on a whole new plate.
While its hard to compete with the raw power of dedicated wall decks, dedicated vespyrs have their own appeal and can be a bit faster. The first variant favors aspects to give the deck a strong control angle, the second one goes all in on abusing Vespyr buffs including Cryonic Potential which is extra deadly when used on your early turns mixed with a cheap minion and or gravity well.
Vepyrs are a pretty sollid tribe that support each other fairly well. Of course you have the classic Elemental plus snowchaser spam, or how it combos with Bonechill Barrier which summons three walls that are Vespyrs. But more recently we have added wintertide to the mix which is another big buff for elemental and thanks to our multiple ways to summon mass Vespyrs even good old Borean Bear has turned into quite the threat. Add Animus plate to the mix and any Vespyrs on the field can snowball out of control really fast.
The deck also has a fair amount of wall focus thanks to Karas natural synergy with them thanks to her BBs, Luminous charge, if unanswered, is a staggering 15 damage. And should your opponents manage to escape the clutches of the walls they can instead be transformed with your aspects to chase people down.
Wisp is vanars best card of the expansion and is borderline oppressive, which is rather important as vanar has suffered greatly from nerfs and the rotation. But wisp came to the rescue and really pushes all vanar decks up a notch. Wisp not only ramps for you, but it also lowers your opponents mana! And if you dispel, bounce, or transform it, the effect is permanent. Wisp is best played defensively but not so far back it cant get into trade, as Idealy you play with it, trade once, and then transform it.
Between Elemental, Luminous, and Aspect of the Mountain you do pretty decent on AOE, you excel at body blocking and stalling, and developing fields that can overwhelm your opponent quickly. Snowchaser and Cryo mixed with your aggressive gameplan tends to keep you ok on card advantage, although running out of steam and vulnerability to burn are its biggest weakness, but the ability to win games fairly quickly, or push out some pretty devastating lategame combos prevents this from being to much of a concern.
Its a solid enough deck but it was much better during rotations, between the many fields wipes, and powerhouse late game stuff like winters wake back its trailing behind a bit now.
