Oh those Deathstalkers. I love them though their real potential is difficult to achieve in my opinion.
I guess your deck is a lot draw dependent since you need Nova + Unstoppable.
Problem is, if you have bad draws you're waiting some time to get the combo.
That's why I personally think that when using Deathstalkers you should use a combo
that is worth waiting for. In other words, to make up for the damage received up to then.
I think this works best with epinephrine. Since an epi'd stalker deals 4 poison counters + atk.
So if you really want a pure poison-stalker 'rush' you should try to build it in the deck.
Here's a deck I made a long time ago:
Death Ray of LifeA different approach could be something like this: (quickly built, not optimized at all)
Those decks aren't always faster than yours since they're trios. But the speed they have as soon as the combo is out is incredibly high. I achieved like over 30 Poison counters in 3 turns? Not to forget the damage made by the stalkers.
I hope you found at least some inspiration
