If you want to shut off dredging entirely, you’ll need an effect that says players “can’t draw cards,” like Maralen of the Mornsong or Omen Machine. Of course, if she draws her first card normally under Spirit of the Labyrinth, then tries to dredge from a later draw, that won’t work because the second draw effect won’t be possible. However, if she replaces each of her draws with dredges, the Spirit never sees that she actually drew a card - and therefore won’t stop her from replacing her prospective card draws with further dredges. This is great if you can somehow trick your Dredge opponent into drawing a card. Perhaps you can stop your opponent from drawing entirely? Spirit of the Labyrinth, for example, prevents your opponent from drawing any cards at all after the first card each turn. Your opponent will probably choose the dredge effect, which means there’s no longer any draw for Notion Thief to replace. When your opponent tries to resolve an effect that would let her draw a card, such as Cephalid Coliseum, both replacement effects jump in and say “pick one!” to your opponent (the affected player). In MTG, dredge has only been printed on 14 total cards, which is incredibly small and primarily on green/black cards.
This mechanic was given to the Golgari guild as one of their main keywords. Dredge cheats creatures into play through interactions with the graveyard and through discarding certain cards. A player no longer had to rely on tapping land to play creatures and spells to win the fair way. For example, if you control a Notion Thief, don’t expect to be drawing any cards soon. Dredge is a mechanic that was introduced in 2005 with the MTG set Ravnica: City of Guilds. Printed in the Ravnica block, Dredge changed the way that a player could play conventional Magic. One downsideor upside, depending on what sort of deck you’re. I personally enjoy paper play, so I wanted to start recording my weekly events for content as an analog to MTGO league's featuring specific decks. Dredge cards in Magic: The Gathering are powerful tools to exchange your turn’s draw for another Dredge card from the graveyard. But we don’t have much info on how it was initially revealed thanks to its age. The History of Dredge in MTG Dredge was one of the many now-iconic parts of the Ravnica block from 2005. Mainly because it's the only good option, and fairly easy to do. Dredge also can’t be responded to since it’s a replacement ability that doesn’t use the stack. In modern, it's mostly MTGO for many reasons. Which means it’s probably not a good idea to try to use other replacement effects to stop your opponent from dredging. There is a lot of MTG content for gameplay. The dredge ability seems a lot like a trigger, but it’s not - it’s a replacement effect that modifies the event of drawing a card.
