Neera, Wild Mage, and Displacer Kitten

Prerequisites

• Neera, Wild Mage on the battlefield
• Displacer Kitten on the battlefield
• An additional noncreature nonland card in hand
• Every nonland card in library can be cast as a noncreature spell with valid targets
• Enough mana available to cast the noncreature nonland card in hand

Steps

2. Neera and Displacer Kitten trigger, as do any Storm abilities or other cast triggers of the spell
3. Resolve Displacer Kitten's ability, blinking Neera

5. Repeat from step 2 any number of times, until you choose to resolve a spell in step 4
6. Resolve all cast triggers created in step 2
