Trample
Whenever Bowser, King of Koopas attacks,
exile all creatures you control named
"Koopa Troopa" and create that many 2/2 red
turtle creature tokens with flying and haste
named "Para-Troopa", then create a number
of 1/2 green turtle creature tokens named
"Koopa Troopa" equal to Bowser's power as
this ability resolves.
