What is your favorite Hidden commander?

So for those that don’t know, a hidden commander is a card in your 99 that is your “actual commander” your deck is built around and your “real commander” exists solely for colors or to get your “actual commander” out. A common “hidden commander” deck type would be KEllan Sunforger where the “actual commander” is Sunforger, and KEllan solely exists to tutor it.

For me, my favorite hidden commander deck I have made is a 5c [[Ink-Treader Nephilim]] deck where I used [[Esika, God of the Tree]] as my commander. I specifically cast her back side, [[The Prismatic Bridge]], to tutor him out as he is my only “real creature” in the deck. The rest of the deck consists of token generators, ramp, pillowfort, and spells that target a single creature or permanent. One of my favorite combos is him + [[Bant Charm]] to tuck away all creatures in the board, then using bridge to get him right back xD.
