Paralyzing Mushroom

If a monster(s) that was originally Thunder is sent from your hand or field to the GY, even during the Damage Step: You can Special Summon this card from your hand. If a Thunder monster's effect is activated in the hand, while this card is in the Monster Zone (except during the Damage Step): You can Special Summon 1 "Paralyzing Token" (Thunder/DARK/Level 1/ATK 0/DEF 0). You can only use each effect of "Paralyzing Mushroom" once per turn.
