There are six-drops that pack more power, but few that pack this kind of punch and are this hard to deal with cleanly
If the descend X ability is a triggered ability with a conditional clause (if this happens, do that), you can prevent the ability's resolution with graveyard hate before it resolves
The cards here are more broadly useful, too, so I could see this being the most popular of the three drops by far
You cast something the table immediately decides to Terminate
The combination of its stellar in-game performance and relatively lower prices makes Lugia VSTAR a must-have for any Pokmon players collection
So yes, this is just great because, instead of needing a lot of complex pieces to pull out a very high attack and KO the last VSTAR Pokmon, you can simply ignore everything, wait till your opponent is about to win and steal the victory right away from them
