The biggest vote against Seaswift is that there are so many other cards that perform similar functions: Ascending Aven, Mistform Dreamer, Keeneye Aven, Gustcloak Harrier, Dive Bomber, Aven Redeemer, Wingbeat Warrior – and those are just the commons. Whereas Echo Tracer is the only common bounce you will find.
