Rulings
- Because it modifies ATK, "Miracle Locus" can be activated in the Damage Step. But not during damage calculation or any point in the Damage Step after damage calculation.
- Even if control of the targeted monster shifts to your opponent, it is your opponent who takes no Battle Damage this turn from battles involving the targeted monster.
- The target of "Miracle Locus" can attack up to 2 monsters, or can attack directly. It cannot attack a monster and then also attack directly.
- You can combine "Miracle Locus" with "Double Attack" and the monster can attack twice. In which case it could attack 2 monsters, or it could attack a monster and then attack directly, all with the +1000 ATK gain. However, your opponent would take no Battle Damage because of "Miracle Lotus’" effect.
- You can target monsters with "Miracle Locus" that could otherwise attack multiple times (in order to give them the ATK boost).
- Your opponent draws 1 card when "Miracle Locus" resolves.
