Last year I've quasi won a game (stopped before end) with an awake Dagon and a simple W9 bless (my scales were dom 9, mag1, cold 3, turmoil 2, luck 3, prod 1, death 2 iirc). I took luck/turmoil because units are cheap and you have more use of gems than gold with Atlantis (death summons + ice guards are invincible if you can afford a wolven winter to prepare the province).

I found Dagon a great trampler even without high reinvigoration because (unlike the great mother) he don't need an armor (and against indie 8 I never had trouble to find provinces he can take alone even without items and before any spell is researched).

The speeded assartut with an high dammage weapon are terrible too (and don't really need arrow protection when they start behind walls of ice guards and undeads).

But in fact it was mostly a good game because I started near LA Ermor and rushed him (with all the mages priests, and most troops able to hit ethearal, Atlantis is probably the best nation for that, only equaled by astral powers) then with a crazy gem income (15d of Ermor + luck/magic) I focused on conjuration and enchantment (both leviathan and catoblepas are great, as well as bane lords with quickness boots, and you also have unfrozen and spectres for diversification - I then found wizards and druids and ended with all paths but blood).

IMO one of the biggest weakness of the nation in MP is the size of the good mages, when you have no other size 4+ recruitable unit. Expect all opponents to fire large monsters (very bad especially when they use black bow of botulf etc). I had hard times against Man using lots of magical ranged weapons, untill I started to use size 6 leviathans in big ice guard squads (fire large target a squad with large monsters but hit random units in this squad, so ethearal crossbows etc... often just kill a guard).
