The way its cards chain together makes it that smidge more complicated than the Amber and Sapphire deck above, so its recommended for those players who already know the basics of Lorcana and are looking to dive into its more advanced strategies
Interestingly enough, another reason why some might be taken by this card could be entirely accidental
Raihan is situational, but thanks to Starbirth, we can find it when needed, and its typically used if our only Pokmon with an Energy was KOd after our first turn, as we can accelerate an Energy and still attack on turn 2
Giving your flying artifacts +2/+0 and trample on top of drawing a card or some other combination is really sweet
It also protects against abilities that target it, such as from planeswalkers, artifacts, or enchantments
