Phelia, Exuberant Shepherd

The blink is the disguise; the counter is the point. Attacking with a two-mana body and flickering one of your own permanents reads as value: reset a creature to clear damage or auras, re-trigger a permanent's enter effect, then collect a +1/+1 counter when the card returns under your control. Because the exile is fixed to the declare-attackers step, it happens on your turn, on your terms; the return waits until the next end step, so the growth accrues one swing at a time. That turns a fragile 2/2 into a clock that hits harder each combat while still doing chores between them. The dual-purpose targeting is the sharp part. Point it at an opposing nonland permanent and you strip a blocker for a turn (a Fog-adjacent tempo swing on the attack), but the card comes back under its owner's control, so no counter. Point it at your own creature and you build a bigger body while banking the value. The one line to internalize: tokens exiled this way cease to exist and never return, so blinking your own token whiffs on both the recursion and the counter. Flash still matters, letting Phelia sit up as an ambush blocker or land at end of turn to swing next combat, so she never has to be committed onto an empty board. It is a compact expression of white's blink identity folded into an aggressive frame, where the incremental growth is the wrinkle earlier flicker-a-thing utility creatures never carried.
