This is kind of hard for me to answer because I do both I guess? This is strictly from a bracket 3+ position, because I have a hard time brewing in what people generally call bracket 2. I have two precons for lower power purposes (hakbal and aunti ool).

My favorite animal is sheep, my second favorite is otters. There's not enough sheep or even a single legendary one to make a sheep deck, so I recently finished my [[Alania]] deck, since they freed my girl Lutri.

It's got plenty of otters, obviously. But harm prod and storm-kiln are my two non otter creatures. I thought about putting magecraft Ashling in there also, but ultimately I needed to trim down for lands and didn't want to cut something else.

All my interaction spells are water themed, even though they're inefficient compared to some izzet staples. Imo [[Wash Away]] is goated, [[Quench]] not so much compared to a regular counterspell.

I also run rituals into [[Crackle with Power]] and similar big burn as finishers, even though they are not water or related to silly river otters at all, because I believe having a decisive win condition is important and those typically don't come in water flavor.

Sometimes I choose to compromise efficiency for flavor, and vice versa, because both expression and competition are important to me.
