I like that this has Haste... I'm not sure how relevant the "Can't be countered" is, but protection from Blue is nice enough.

Well if it gets played outside of Standard the "Can't be countered" part is really relevant and with it's abilities I could see it being played in ramp deck or maybe as a finisher in elf combo.
