The same is true for copies of spells that were put into your graveyard when they resolved or were countered

Basically, according to Wizards ' own thoughts back in 2015 and the consensus view of the community, the London mulligan rule seems likely to power up two of the most problematic and least liked aspects of the Modern format, and this doesn't even take into consideration that certain cards or decks can directly abuse the rule (most commonly cards or combos that actually want you to have fewer cards in hand, like Restore Balance or Ensnaring Bridge, both of which happen to win by making the opponent unable to play a full game of Magic or, in the case of Restore Balance, any form of Magic at all)
Combined with Medallion Weights or Queen of Hearts Sensing Weakness, constant challenging of opponents can draw you cards too
Weve only seen one Otter so far, in Bria, Riptide Rogue, but already its clear that the creature type will care about casting noncreature spells
If you tick those boxes then this is one of the better payoff cards but that is happening like a couple of percent of the times you play this deck at most
