I like transmute effects. Are there any available in standard? {Muddle the Mixture}
Transmute was Dimir's keyword from the original Ravnica set. They only appear on Dimir cards from that set, so no cards with transmute are in standard. I agree though, I generally like the effect.
Ya, black transmute is one of the many ways my buddy gets {Necropotence} out so frequently in his mono{B} EDH. Sooo annoying lol
