在每个结束步骤开始时,在每个不由你操控的生物上各放置一个黏菌指示物。
对每个不由你操控的生物而言,其上每有一个黏菌指示物,它便得-1/-1。
每当一个不由你操控且其上有黏菌指示物的生物死去时,你派出一个1/1黑色蛞蝓衍生生物。


,牺牲一个蛞蝓:抓一张牌。
Toxrill. the Corrosive's second and third abilities apply to all creatures you don't control with slime counters, even if those slime counters came from a source other than Toxrill's first ability.
Another card, Sludge Monster, causes non-Horror creatures with slime counters on them to lose all abilities and have base power and toughness 2/2. If you control both Toxrill and Sludge Monster, those non-Horror creatures are 2/2 creatures with no abilities that also get -1/-1 for each slime counter.
Toxrill's third ability triggers when a creature an opponent controls with a slime counter on it dies for any reason, not just due to its toughness being decreased by Toxrill's second ability.
