If you want to one-button Draw and Play you can use a macro. The only issue is that can't try and use Draw to change the card b/c Redraw still didn't provide one you wanted for Astrodyne. I'm not good enough to be that granular in the card decision process and if say you have two range dps and got another melee buff card with redraw, it's going on the tank. Anyway the macro I'd use your be:

/micon Draw (better to see draws avail, then likely redundant card drawn)
/merror off (this is so you don't see red error messages for the other activations, leave out until you know the macro works)
/ac Play <mo> (I use mouse over so I don't have to click target, but just have pointer over their bar in party list)
/ac Play (for solo so it targets myself or selected target, though relies on pointer not being on a target you can use play on)
/ac Draw (Draw is activated if no card to Play)
