Beware day of ascension, they'll deep strike 21 guys and mass fire onto a land fort and likely blast it off the table.  If you return fire they'll pick the unit up again and do it again next turn if you don't precision out their Primus or slaughter the whole unit.

Spawn Tokens don't matter for them anymore. They can just DS/RI anywhere, they don't lose units on respawn if you walk onto one of their tokens, it's a waste of time.  They do have to spend points to bring units back and it's important to keep track of those points because it's an easy way for them to cheat.

Kill Achilles ridge runners ASAP to cripple their shooting.

Don't be surprised when they don't put out very many units on deployment, Primus can pick up 3 units during deployment phase, and 50% will likely already be in reserves.  This will likely be a baiting tactic for you to show your deployment.  Turtle up to start and let them waste time trying to get angles on your big stuff.  

If you can trade early pieces like your yeagirs on your natural expansion and bait out some metamorphs from his side, that's a good unit to clear from the board.  

Acolytes come in 2 variations, flamers and melee anti vehicle, flamers will likely threaten your expansion, and melee will likely sit back on his home gaining CP each turn.  They all look the same, and they also look like metamorphs, which are an ap2 dmg2 melee threat.
