Cup of ace

I`m too lazy to test it on the psp so I decided to ask here ^^". If I send Cup ot Ace to the grave with Diamond dude's effect... what happens next turn ? =D Do I toss a coin or just draw cards or idk x3

You must Toss a coin

Cup of ace rulings : Tossing a coin is not a cost. The coin is tossed when cup of ace resolves.
