Normally using so many cards to Summon a single monster would be considered a waste, you would likely leave yourself completely open after this play, but with Obelisk it’s sort of different: this card’s immunity to targeting effects prevents your opponent from taking control of it with an Enemy Controller or from destroying it with a Koa'ki Meiru Maximus or a Vampire Kingdom.

If you have Double Summon available, the combination of Junk Forward and Junk Synchron can also lead into Obelisk the Tormentor.

If you Summon Junk Destroyer this way, you will get to destroy up to two cards on the field. This page notes details of Obelisk the Tormentor (DIVINE/Divine-Beast/Effect Monster) : decks, tips, effect and rulings. You can Normal Summon Junk Synchron, Special Summon Dark Verger (What Grows in the Graveyard) from your Graveyard via its effect and then Special Summon Armades, Keeper of Boundaries or you can Special Summon Junk Forward from your hand, Normal Summon Junk Synchron, Special Summon Dark Verger from the Graveyard and then Special Summon HTS Psyhemuth (Junk Synchron + Junk Forward) or Junk Destroyer (Junk Synchron + Junk Forward + Dark Verger).
