If you control a monster whose original name is "Obelisk the Tormentor": Negate the effects of 1 Effect Monster your opponent controls, and if you do, destroy it, and if you do that, for the rest of this turn, the effects of that monster are negated, as well as the activated effects and effects on the field of monsters with the same original name, then, if you activated this card during your Main Phase, you can apply this effect
It has a similar effect to Garoth, in that by detaching an XYZ material you can mill the top 3 cards of your deck, while drawing a card for every Lightsworn monster that was milled this way
The card is a mainstay of the Modern format and has recently been unbanned
The Structure Deck's new extenders allow the deck to take a card out of the opponent's hand five times in the opening turn, meaning that the opponent will often start their first turn with no cards to play
While the individual sets change, these prices are consistent with Standard set releases
