Check this out on the rules for split cards from “saturday school” with Judge Carter
Q: The split card Odds/Ends is imprintable on Isochron Scepter, correct? Once imprinted, can both halves be played? --Mason S.
A: At least one half (Odds) is both an instant and has converted mana cost of two or less. You can imprint the card (Odds/Ends) and play either half when the Scepter’s activated ability resolves.

Q: Can you use Sunforger to search for Odds/Ends? If so, would you be able to play Ends? Or would you be forced to play Odds? --Nop J.
A: Like questions about Isochron Scepter with Odds/Ends, at least one half qualifies for Sunforger’s ability. You can search for the card because the Odds half is valid, and then as you play the card you’ll choose which half is being played.
