Wavering Eyes is a great Quickplay Spell Card. It's good in decks that run Pendulum Monsters and good in decks that play against Pendulum Monsters. Once it's activated, it destroys all the Pendulum cards in all the Pendulum Zones. Then, it counts them and applies effects in sequence based on the number destroyed. Destroy 1 and inflict 500 damage. Destroy 2 and inflict 500 damage and search a Pendulum Monster to your hand. Destroy 3 and inflict 500 damage, search, and banish 1 card on the field. Destroy 4 and do all that plus search another Wavering Eyes to your hand. There is no restriction on how often you can activate this card. So if you destroy 4, you can use the second Wavering Eyes to at least inflict the 500 damage from the 2nd effect Pendulum Monster that you searched. Just remember, if you're using this against Pendulums, you have to activate it before they declare the Pendulum Summon of monsters. 

Score: 4/5 It's chainable and has good effects.

Art: 4/5 I just love this artwork regardless of it having nothing to do with anything Pendulum.
