Ok i see one potential way that this might not work...but as long as floating/resolving effects exist independent of their card...
+
So i have reanimated in play. I play Darkness blade, E with darkness blade, next E, lift and redrop reanimated. Once it leaves play, it is no longer the same card, so next E i lift and drop reanimated again.

Profit (by committing out my opp)
this work?
