That's a little better but perhaps have an "until the End Phase" clause, or maybe force the Gemini back to your hand?

I dunno. The thing is, it requires no monsters for the effect to be used, and if I happen to have only Supervisor or some high-level Gemini monster in my hand, they're basically dead draws. I'll wait for Ammokkx to deliver the final verdict.
