It will help you copy those spells with its first ability and then keep growing bigger each time you copy a spell with its second ability

It fits go-wide decks, blink decks, cat typal decks, and the like just with this ability

Blue has some lovely things but they are either all double blue and hard to include or only the kind of thing you play when you are already in those colours rather than being worth splashing for themselves
