Spontanzauber
Die Zielkreatur erhält Erstschlag bis zum Ende des Zuges. Ziehe eine Karte zu Beginn der Versorgungsphase des nächsten Zuges.
You may target any creature, not just one that doesn’t have first strike. If the targeted creature already has first strike as Lightning Blow resolves, Lightning Blow won’t affect it (since multiple instances of first strike are redundant), but you’ll still draw a card at the beginning of the next turn’s upkeep.
