Mistral Soul Eater
Instead of playing patiently to build up a big Soul Eater, this deck aims to go on the attack and get Tempo Soul Eaters in play.
Seed accelerates lands and lets you get Deserts in face range. Iona's Smile and Prayer accelerate draw.
All removal is creature based to buff the Eaters.
Mulligan for Seed, Mistral, Carassius. Start with a central Forest for Seed of Paradise. This lets you go out to both sides. You want to play a Mistral Guide on the opposite side then start launching Salmon at face. The opponent has to react to them and this keeps your backlines safe.
Drop a Soul Eater as soon as you can and hopefully it's GG.
