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
Perhaps this card could see some fringe play in decks that use the graveyard a little bit, but that might be asking too much considering Gurmag Angler exists
The Big Score wont affect Limited as much as Breaking News, since only about five List cards appear in any given Draft pod on average, and theyre not even guaranteed to be cards from The Big Score
Both the spell and the resulting creature are colorless and have a mana value of 0
While this Otter lord isnt quite that oppressive, this cards static ability of being able to toss off noncreature spells on your foes turn can certainly be massively advantageous in the right deck
