Tips for Joker

After recently getting the smash DLC and playing Joker I love him. He feels like a mix of everything and especially like Greninja (who was my main) but I want to know if there is any other tips for combos/strings with him. Here are his current combos/strings I know.

Down tilt into up tilt/up air at low percents

Up air into up air into up air....

Down throw into fair at low-mid percents

Down throw into up air at high percents

Up throw into up air at low percents

Up b into fair at low percents

Up b into up air at mid percents

First hit of fair into side smash

Dash into dash on some characters

Are there any other really good ones I don't know. If so, I'd appreciate it if you would inform me. Thank you!
