It would be also important to note that akroma's vengeance still does not have the cost efficient range to bypass gaddock teeg. Which should be looked considering I could see more threshold players utilitzing teeg in their respective sideboard. Especially when they want to have a better chance against the rising of UWb landstill.

Pernicious deed is probably the most logical alternative to engineered explosives as Clemens stated previously. Clemen's 4c landstill can make full use of deed considering his deck has a flexible manabase and you have easy access to any color you want via E. dragon and multiple fetchlands. Also the fact that dustbowl would seem awesome to me with life from the loam.
