Grand Bombardment (神砲撃 ; shin hōgeki) is a keyword introduced in SD46, exclusive to The RedThunderGodKing Revol-Tiger-Z. The effect is worded as follows:
- Grand Bombardment (When Attacks) You can reveal two cards from your Deck. For each "Z"/"Steel"-named card among them, put a core from the void to any Red Grandwalker Nexus you control, and send an opposing Life to the Reserve. Those cards are added to your hand.
Grand Bombardment is an alternative version of Bombardment, adapted to the Grandwalker meta and the Red/White archetypes of its release, "Z" and "Steel".
