In practice, only one dredge card, Life From the Loam, was actually cast for (this is important) its intended purpose, while the rest were simply not worth playing because why would you want to get a subpar card every turn
1x Foil Marwyn, the Nurturer
Financially, its very inexpensive
Cultivate, Kodamas Reach, and Yavimaya Elder are more ways to put lands in hand to increase the odds of a double land drop turn
Wasteland Strangler and Bearer of Silence are more examples of creatures that serve two purposes
Shark Shredder, Killer Clone I wish the sneak was a little lower costed, but Shark Shredder will win the game if the opponent isnt ready (imagine doing this to a reanimation player before they can get their big thing back from the graveyard)
