Thanks for this, especially the discussion of hidden zone vs public zone rules, that's important to know! It's not very reliable but it is fun, I think it's slightly underrated in commander in decks that want to play rituals and/or have goblin synergy. It being a creature I think it gets even better if you're running Panharmonicon-style or creature copy effects.

This was super helpful, thanks for breaking that down

The way stickers work I doubt it's worth it to base your win con combo over this card, but it's a very interesting creature if your deck can gain value from even getting consistently 3 mana back, with the chance of getting 4-6 once in a while. I guess that in a mono red commander deck this is actually quite nice.

Krenko mob boss is this cards home. Turn one three mana is easy for that deck. Using blank goblin to to get to 4 5 or 6 for a turn 1 Krenko is pretty strong. Plus blank goblin counts as a goblin.

_____ Goblin so far the only use i can see it doing is with Grenzo, Dungeon Warden and having The Cauldron of Eternity on field. Regardless of what sticker you make use of as long as your gaining three mana (and your going to at least gain four) you basically would use _____ Goblin the same you would Priest of Gix or Priest of Urabrask in Grenzo. Activate Grenzo, Dungeon Warden's ability to pull _____ Goblin or Priest of Gix or Priest of Urabrask from the bottom of your library to the graveyard, oh look Grenzo, Dungeon Warden's power is higher or equal to the creatures power, so we put the creature from the graveyard onto the battlefield. Sacrifice the creature having net at least one mana using two of the mana to repeat. Once you have about a billion mana you can sacrifice Grenzo, Dungeon Warden, cast him where X is one hundred, then put your library into your graveyard but all your creatures onto the battlefield. If somehow you don't win your ability to "draw a card" for draw step is reliant on retaining The Cauldron of Eternity. Everything else that would LOVE to run _____ Goblin to slap the Delusionary sticker on it needs to know using the Delusionary is gauranteed, and it would be nice if WotC changed the rules so you can pick what sticker sheets your using but i understand why what sticker sheets you can get is randomized for each game, however, this just means that the sticker creatures are only ever going to see niche use like with Grenzo or "fun play" like with Ambassador Blorpityblorpboop as commander.
