Deldar & Kin 2500 pts, Assualt is DED

Going down to a semi-competitive tourney at the end of the month and I wanna teach all those Tau players a lesson that assault is not dead (miss spelled "dead "on title on purpose lol) Here's what I'm taking.

The plan is to put the Archon with the Grots, Baron & Farseer with the Beasts. Have the Avengers surge foward T-1 and lay some very close fire on the opponent giving the Wych, Archon & Farseer units time to catch up to the melee.
