For my pendulumdeck's test I am trying all possible duo's, unupgraded, in this order:
,
,
...
,
,
...
Etc, you get the point.
I am no at
, meaning I have tried all death duo's, and there were only 2 deathstalker deck's in 13 decks (I have made 2
decks), however, there where 7 decks involving poison (with or without deathstalker).
The only deck's using deathstalker were
, and
.
Side note, when talking upgraded, I would have used chaos power + deathstalker for
, and maybe eclipse + deathstalker for
.
The point is, especially the unupgraded deathstalker is really weak, because for unupgraded there are only 2 reliable duo's. Chaos power only works upgraded, and nightfall isn't worth taking, because the 1 damage is to easily blocked, and you might never get the card (you don't want to splash 6 nightfall, but 6 momentum isn't a problem).
I would say, the unupgraded deathstalker needs (at least) a HP buff, and I am against an attack buff for the upgraded, because that would make the difference even bigger.
I really like the 3 poison ability, or the poison on death, which would be even more fitting, and would make people think twice before killing it.
