What do you think about teleporting a buffed firelance templehost over the soulscream bridge for a first turn charge? Could it work? Worth it? The knights would have +4 on the charge roll
Coaleced get more attacks and will do more mortal wounds with the starpriest ability. Starborne can only teleport one unit with LoSaT and dont get plus to charge from their version of the firelance
Against certain armies could work (SoB, for example, where you will hit a juicy model), but in other cases it won't. The opponent will see the cavalry and the bridge, and will just screen the possible targets. Of course, you could do it the same, sacrificing the unit which will be alone in the enemy lines, but will distract the opponent giving you more time to gain control of the battlefield with slower units. Let's say that it depends a lot on the army you are facing, the scenario and so on.
I just don't think it does enough for the 100 points its going to cost you. Armies that want bridge are armies that don't want to move or get benefits from not moving. It's also only ever going to be an advantage on 24'' deployments, and only if the other dude is literally lining up on the line. I just think it's way too situational to want to build a competitive list around. I've done it before with a bunch of warriors through a bridge and its hilarious and fun, but I don't think it's worth it personally.
