When this is in play, not only will you be creating twice as many tokens, but anything that gets a counter will also be doubled as well
The game expects you to ramp into this attack with cards like the Baby Pokmon (whose attack attaches Energy to your bench for free) and Ho-oh ex (whose attack generates exactly the three Energy types needed by Lugia), since the game's random Energy generation means that just being able to use it once without these effects is a pipe dream at best, and only getting it off a single time probably won't even win the game
That token gains haste until end of turn and attacks this combat if able
