Time-Stutter Mage

Echo - Return another creature you control to its owner's hand.(At the beginning of your upkeep, if this came under your control since your last upkeep, sacrifice it unless you pay its echo cost.)
Whenever Time-Stutter Mage enters the battlefield or its echo cost is paid, you may return another target creature to its owner's hand.
"Time demands balance. If I enter the future, another must fill the temporal void I create."
