Perhaps Widow Queen in light of the upcoming Matron Velenne ?
LOL Def a candidate for “Essest” S-tier.
Sad, but maybe true. [spoilers]
At least with Widow Queen, you could consider running her together with Velenne, who only hits one target, for her all-enemy damage. With Grapplepot, in any situation you’d consider running her, you’d be better using a second Gobtruffle.
It’s really a shame, I’d like sacrifice-style troops like Widow Queen and Vash to be viable, they provide such a different style of play. Unfortunately, too many modes penalize player deaths for it to be worth all the work to make these troops work, especially in light of easier-to-use troops who do the same things.
Regarding Sekhma, this team took me through a large part of the mid-game, I don’t use it any more because I need Hero XP, but it was a very capable team
