Thats also totally viable-Phase Ready mod is a really really good one to put on something when you want to do it every turn I think, there's also the Paracausal Mod from the Saladin which gives Overkill (1 heat/re-roll when a damage dice comes up as 1) and the damage cant be reduced in any way. The way I can see the turns breaking down for you is definitely maximizing positioning early on in order to offset any high damage Ordnance rifles/weapons you might want to mount. If its an outside of deployment zone objective you'd probably want to try and nab a high spot to take advantage of Mag Clamps
