Then make it an earth card or something.
Otyugh can't do a death trigger if it has nothing to eat, but it's still so much more useful in general. And if you do have a boneyard, it's not hard to feed the oty. Viruses are an automatic death trigger as well, and they don't even require an off-element at all. White snake can repeat its ability, but again, is that skeleton, vulture, or bone wall really a big threat? With only a mark, the ability is only usable once per turn anyway. An oty and two phoenixes can do unlimited death triggers too, and that combo is "only" three times larger.
Rage potion, lightning, freeze, rewind, bolts, devour, mutate, lobotomize, holy flash, gravity force, will all do it for control. And even ignoring the snake, plenty of other deaths could be going on already.
I'm not saying a 2
cost isn't fine, I just don't think 1
is OP.
