If you’re playing a multicolored deck and want to destroy only permanents of a specific cast cost, Engineered Explosives are designed precisely for this task at hand. Simply the # of different colors you used to pay for X will equal the casting cost of all permanents that’ll be destroyed when you sacrifice Engineered Explosives. If that sounds confusing, let’s say you tapped an Island, a Forest, and a Plains so you have 3 different mana types. You use those 3 mana to cast Engineered Explosives and when you activate its ability, you’ll destroy all permanents with a casting cost of 3.

My Final Thoughts
The effectiveness of this card is highly situational so it’s no surprise most people include it on their sideboard. If your opponent has a TON of permanents with a casting cost of 1 or 2, this can come in handy.
