This deck is pretty straight forward, but for notes, recursion is a big way to use this deck.
Xenan Lifespeaker benefits off of recursion a lot since you can reuse the ultimate again and again. For games where I don't draw other untis, I just win by using Xenan Lifespeaker as a huge beatstick.
Additionally, if a unit dies and it doesn't have Lifesteal, recurring it from the void will give it Lifesteal while Xenan Lifespeaker is in play.
I put in
Acantha Ascending but I have also found that [VeteranMercenary[/card] and
Silverblade Menace work pretty well too. It's really based off of preference. If you do want to add in a Market, I would suggest removing
Acantha Ascending as not too much changes in terms of deck functionality.
