The combo can be executed with only a few cards, which makes it quite simple as well: Cast Venture Deeper , targeting your opponent Cast Merfolk Secretkeeper from adventure zone Cast Ashnods Altar Cast Chromatic Orrery to turn colorless mana into blue mana Cast Lier, Disciple of the Drowned from the commander zone Sacrifice Merfolk Secretkeeper , using Ashnods Altar Cast Venture Deeper from graveyard, using Liers ability Repeat this cycle infinitely until your opponent mills all their cards in a single turn using the mana produced by Ashnods Altar and Chromatic Orrery
Effects like Tectonic Instability and Price of Glory force action from your opponents on their turn, making them effectively play at sorcery speed or suffer the consequences
It also fits pretty well in Scry builds, like the Tales of Middle-earth Elf decks
It doesnt matter what they kill, because youll be able to make more of something else
(If this matters, you must have a very good reason for wanting to pay life.) If the target Equipment can't legally be attached to the target attacking creature when Raubahn's last ability resolves, the Equipment won't move
