Terrible inclusion in Regidrago. The first attack is outdone by other shred options, and there’s like no point to the second attack since it means you already had enough on board to start attacking with Regidrago in the first place.Tatsugiri's attack is kinda busted. It could work with Regidrago,somehow.
If I had a nickel for every time I talked about why not to use a tatsugiri in Regidrago, I’d have 2 nickels.
