Rebound and text-changing effects
The recast copy will not be affected.
When a spell with rebound resolves, it is exiled as the last part of resolution. It therefore becomes a completely new object. When it's cast again the next turn, the new spell has nothing to do with the original one.
The new spell will therefore not be affected by any effects affecting the original one, be it text-changing effects (Sleight of Mind) or additional costs paid for the original spell (overload).
