@FORFUN I'm relatively certain that you just participate as normal. I'm not aware of any rule that says you can't use the mechanics you chose yourself.
Etherealize (If this creature would die, put an ethereal counter on it instead. As long as this permanent has an ethereal counter on it, it isn't a creature.) created by Temurzoa
Winners and mentionables, each of you can choose up to two custom mechanics for future challenges. Pick any mechanics you can find in Mechanic Encyclopedia for ALL or Tome of TheMechanix, or you can make new mechanics! Comment on this thread or send me a PM. If you don't want to choose, that's also ok!
Thanks Tomigon! I’d like to choose two of my own mechanics please: Submerge - COST(Exile this card and up to one other face down permanent in a face-down pile. Shuffle them, then return those cards to the battlefield face down. Submerge only at any time you could cast a sorcery.) As seen on: https://mtgcardsmith.com/view/icefang-naga
Epiphanize N(Look at the bottom N cards of your library, then put any number of them on the top of your library and the rest on bottom in any order.) by @CnBCustoms
Erupt(You may cast this spell from your graveyard. If you do, change its text by replacing all instances of numbers to "1". Then exile it.)

I struggled on the subtypes, but I eventually came up with this. Thank you, Abaa, for this amazing ability.

Terribly disappointed I couldn't fit in that this would have protection from blue Oyster Cultist creatures as well...

Here's my third entry for Retaliate by @Aggroman15.
It's time to announce the winners!
1st Place
Ninjutsu+hunt is very cool!
Super adorable! I think it doesn't need to be green though!
Farhaven Rootdrinker by @Jadefire
That seems like a bit too many words, but I think the card is useful and interesting!

Forgotten [cost] - (As long as this card is face-up in exile, it has [Cost], Turn this card face-down: [Effect].)
Cosmic (This enters the battlefield phased out.)
Also, in the Honorable Mentions section, you say that Ripe for the Plunder was made by me, which it wasn't...
Sleepwalk by me (This creature can block while tapped. If it would die during the turn it blocks this way, exile it instead.)
-and-
Meek by @CrucibleOfHate (This creature cannot attack or block alone.)
