Totally depends what deck you run and cards you already have. It's a great card in some decks for sure and always pretty handy, but the same can be said for quite a few of the options.
Yeah sphere kuriboh. Nope just keep your 1 copy and find some other UR to pick. Choose some universal card , some card you know will keep coming back in meta. Be wise.
King of the Swamp is an example of universal card for fusion decks, which will be very powerful as the GX era isn't over yet and we still haven't got the best fusion deck in GX - Cyber Dragons, not the core card anyway.
