This lines up a little unusually, however, as unlike Charizard, Mewtwo, and Celebi, in Dialga's deck the Pokmon you want to be stacking energy on is likely not the Ex but the regular, one trophy monster
Ultimately though, the best Link monsters are stacked full of effects
Scion's effect only costs two mana, so turning it into a powerful creature out of nowhere can be a game-ending effect
It's also a "may" ability, so they don't have to worry about accidentally killing him
Vexilus Praetor grants this to all of your commanders
