Prixis Killers

Prixis allows you to search for your Dawnwalkers using your Ephemeral Wisp blocks, you're fine if you toss any wisps, walkers, Vodakhan's, or standards into your void. Use your Echo spells as you draw them (you're not using them for anything, they're just fodder for Rolant's Memorial unless you get truly power screwed); some power turns into spells as the curve tops out at 5, more power turns into additional overwhelm units.

Cast Xenan Initiation / Striking Snake on any overwhelm units you've hit with Rolant's Memorial and select low-health enemy targets to send through maximal damage to your opponent's face.

Higher brackets may find it worthwhile to add 3-4 cards more of removal—I'd suggest simply Vanquisher's Blade, or possibly 1-2 Harsh Rule in a meta that heavily favors tokens.

If you find the meta is faster than you are, try swapping out Argenport Crests or Temple Standards for sigils.
