Exploit

Exploit is a keyword ability introduced in Dragons of Tarkir, where it was the signature ability of the blue-black Clan Silumgar.
==Description==
When a creature with exploit enters the battlefield, the player may sacrifice a creature. Each creature with exploit has another ability that gives the player a benefit when it "exploits a creature" This means when the player sacrificed a creature because of its exploit ability. <c>Henry Wu, InGen Geneticist</c> and are the only Exploiters that track the qualities of exploited creatures.
Exploit will allow you to sacrifice only one creature. You don't have to sacrifice a creature, but if you do, you choose which one as the exploit ability resolves. You can sacrifice the creature with exploit to its own ability. If that creature has an ability that triggers "when [this creature] exploits a creature," sacrificing itself to its own exploit ability will cause that ability to trigger. And finally, the creature with exploit needs to still be on the battlefield as you sacrifice the creature in order for that "when [this creature] exploits a creature" ability to trigger. If it's not on the battlefield as its exploit ability resolves, you can still sacrifice a creature, but you better have another good reason, because that last ability won't trigger.

It was also featured as a cameo in Modern Horizons, Modern Horizons 2, Fallout, Jurassic World Collection and Modern Horizons 3. Through the last three appearances, Exploit branched out into all five colors, albeit in gold for two of those three cards.
