Infection Hazard (S-BT02A-SP/0014EN) (S-BT02A)

[Set] (This card remains on the field)
"Plague" spells you cast cannot be nullified.
When you cast a spell, choose up to one "Plague" monster or item on your field, and drop the top card of your deck. If the card dropped is a "Plague" spell, you may put that card into the chosen card's soul. This ability only activates once per turn.
