This would be fluffy list but I think this list would definately need reavers to stall your opponent early turns and use chariots to stall your opponent middle turns.
Such a big unit of seaguards would be easily countered by anything fast and with only str 3 they will really hard time fighting anything with better toughness or armor save. Unless you manage to use Okkams Mindrazor on them, but I wouldn't count on it too much.
