The Warhammer 40k decks had some really interesting options should you want to give Alela a little more midrange potential
Allowing cards to be played in mono-colored decks is one thing, but in this case any deck could play Beseech after the change, since its a hybrid black/colorless card
Marauding Raptor can be risky because it deals damage to your other creatures as they enter, but the only creatures that are insta-killed by that are Otepec Huntmaster, Sakura-Tribe Elder (which you can sacrifice for a land before it officially dies anyway), and the vampire tokens made by Ghalta and Mavren
It's not actually that hard to deal with, but in scenarios where you can't remove it, you're going to have a very tough time winning the game
Both decks lean toward an Aggro playstyle, packing in 26 Creatures each (many of which are double-sided, using Innistrad's Day/Night switching mechanic)
Note that this price spike only applies to the original Odyssey printing of Braidsthe more recent printing from Modern Horizons 2 grew a similar percentage, but still costs under $1 per copy
