Just use future fusion. Send 7 crystal beasts with different names to the gy using future fusion, then summon Rainbow Dragon and tribute for Overdragon.
No, YOU missed how it works. Future Fuse uses Overdragon to send the Crystal Beasts to the GY, then you will have them there to summon the Rainbow Dragon and then Overdragon.
The problem is that if you only have one copy of the Turtle, and that this copy is in your hand... You're dead. Period. And of course, you need to have Future Fusion first turn
