If your opponent activates a card or effect, while this card is a Continuous Spell (except during the Damage Step): You can Special Summon this card [with another effect on top]

When this card is destroyed by battle: You can Special Summon 3 "Legendary Knight" monsters from your hand, Deck, and/or GY, ignoring their Summoning conditions
These include creatures such as Agent Frank Horrigan (indestructible, proliferate), Alpha Deathclaw (destroys permanents), Consuming Aberration (mill), Ezuri (proliferate, card draw), Fathom Mage (evolve, card draw), Lily Bowen (+1/+1 counters, life gain), Marcus (card draw, +1/+1 counters), and many more
