Thrumming Stone + Memory Lapse + Chandra, Hope's Beacon + Displacer Kitten

Thrumming Stone

Memory Lapse

Chandra, Hope's Beacon

Displacer Kitten

How it works

1. Cast any other spell, or wait for an opponent to cast one.
2. If you cast the spell, Displacer Kitten triggers, blinking Chandra.
3. Cast Memory Lapse by paying 1, targeting that spell.
4. Chandra, Displacer Kitten and Thrumming Stone trigger.
5. Resolve the Chandra trigger, creating a copy of Memory Lapse, targeting the original Memory Lapse.
6. Resolve the copy of Memory Lapse, countering the original Memory Lapse and putting it on top of your library.
7. Resolve the Displacer Kitten trigger, blinking Chandra.
8. Resolve the Thrumming Stone trigger from step 3, revealing the top four cards of your library and casting Memory Lapse without paying its mana cost.
9. Repeat from step 4.
