It's hard to answer without context, but I'd probably suggest Psylar. She's just all-around amazing everywhere. Scyl and Cardinal are worthy candidates too.
Also - leave the rest of your 50's alone. Most of the others are really terrible. Fang Cleric may eventually become 60, as well as Skull-Lord and Taurus, but they are all on very specific teams. The others are junk. Don't feed them to anyone, but don't waste any more resources on them.
