I would split this deck into 3 options
Deathstalkers + Momentum --> gets through shields but bonewalls are only real way to prevent being rushed before hte poison starts to take effect
Deathstalkers + Chaos Power --> chaos power sometimes doesn't get enough attack to get over shields but entropy comes with antimatter which is a great stalling card along with discord.
Deathstalkers + PSN --> here you can run a PSN with many types of CC to prevent being rushed and use all sorts of buffs like chaos power, momentum and blessing.
