Verzauberung
Immer wenn eine Nichtspielsteinkreatur, die du kontrollierst, angreift, bringe einen 1/1 roten Goblin-Kreaturenspielstein getappt und angreifend ins Spiel.
Opfere die Vormacht der Mardu: Kreaturen, die du kontrollierst, erhalten +0/+3 bis zum Ende des Zuges.
Although the tokens are attacking, they were never declared as attacking creatures (for purposes of abilities that trigger whenever a creature attacks, for example).
As the Goblin token enters the battlefield, you choose which opponent or opposing planeswalker it’s attacking. It doesn’t have to attack the same opponent or opposing planeswalker that the original creature is attacking.
