Shadowverse

Everyone is talking about a mega-lore support card, but a flute comes to my mind. It might be a meme, but who knows. It opens up new build possibilities for the dragon. Of course, this requires a lot of good fodder.

I don't see any particularly new opportunities yet... Overflows are great, but it's important that there are some effects even on small ODs. This one just has an increased stat of +1, and that's it.
Look at Aila with an effect that allows her to ramp up faster, or the imprisoned dragon with stats of 4/3 for 3. Remember that the dragon generally jumps from two ODs to four quite often and can use Rahab... And it becomes clear that this thing isn't needed on 3 OD.
On 7 OD, when storms are already in full swing, it also seems questionable.
In general, in my opinion, this card is only for the arena. There, you can really connect the flute and go for it. But in ranked play, it's something like a support cannon, nothing more.
