I need to figure out which format and archetype this question is about. Let me start by searching for Elusive Otter and checking recent meta data across formats.
Good, I have the card ID. Now let me find which archetypes and formats are actually playing Elusive Otter recently.
Clear winner: Standard Izzet Prowess. Now let me compare winrates for lists with vs. without Elusive Otter in that archetype.
Here is what the data says, @takhs25453628.
In Standard Izzet Prowess over the last two months (703 entries with Elusive Otter, 1,870 without), the lists that do NOT include Elusive Otter in the maindeck are performing better:
Without Otter: 52.81% winrate (6,097 W / 5,448 L across 1,870 entries)
With Otter: 50.93% winrate (2,109 W / 2,032 L across 703 entries)
That is roughly a 1.9 percentage point gap in favor of the Otter-free builds. The sample sizes are solid enough to take this seriously, though keep in mind this is match-record based (wins/losses per entry) rather than game-by-game match data. The non-Otter lists are also the majority of the field, so the higher winrate is not just a small-sample artifact.
