When Ennis enters, exile up to one other target creature you control. Return that card to the battlefield under its owner's control at the beginning of the next end step.
At the beginning of your end step, if one or more cards were put into exile this turn, put a +1/+1 counter on Ennis.
Ennis is a mono-white blink engine that flickers your best ETB creatures on entry and grows whenever you exile cards during the turn. You curve out cheap value creatures, repeatedly blink them with Ennis and external flicker effects to snowball card and board advantage, then close with go-wide tokens, a Voltron-sized Ennis, or a recurring combo loop.
Two-mana commander that's cheap to recast and protects your key creatures by flickering them out of removal
Turns any blink effect into a counter engine, growing Ennis while reusing ETB triggers
Mono-white access to the best blink, tax, and recursion support without color stress
Flexible: works for value midrange, aristocrats, or counter-Voltron
Mono-white means weak card draw and ramp compared to other identities
Counter growth is slow and Ennis dies to any wrath, resetting the engine
ETB-payoff strategies fold to graveyard hate and creature-light board states
No built-in evasion, so a big Ennis can be chump-blocked indefinitely
