Raphael Tech is just sad, 3cmc is the most you can have the effect be playable (but then it's not really instant, it's a very specific timed sorcery that's also going to bounce something to hand in red, probably the worse ETB color) but discard hand draw 7 is only good if it's me only to synergize with what I wanna do or everyone all the time because I'm going to fuck them with a draw spell hate combo.
I think Turtles Forever would almost be on the verge of being playable (in commander where you can politic with the designated picker) EXCEPT for the legendary requirement. If I could just ask someone to let me get a hate bear to fuck with players 3 and/or 4 I'd be interested but the hate bear population really dwindles with the Legendary Only clause.
