I'm not too experienced, so I might be missing something, but I think only the Sentinels unit OR the Dawnriders unit can be Battleline (not both), since there's only one unit of Wardens. However, since you have Scinari character in the Cathallar, the Bladelord unit can become Battleline.

1.3.2 Keywords states that "Every warscroll includes a list of keywords that apply to all of the models in a unit that uses that warscroll." 1.3.2 Keywords also states "Keywords appear in KEYWORD BOLD in the rules..." 22.6 Keywords says "Sometimes you will be allowed to give a keyword to a unit for a battle. If you do so, treat the unit as having that keyword on its warscroll for the duration of the battle." Vanari Auralan Sentinels warscroll, for example, states "The High Sentinel of this unit is a WIZARD while this unit has 5 or more models." The warscroll is the entire page. The word WIZARD appears on the warscroll, and in KEYWORD BOLD, indicating it is a KEYWORD. The Keyword section only states keywords that ALL the models in the unit have. Only the High Sentinel model in the unit has the WIZARD keyword, so it wouldn't be in the bottom row. But the High Sentinel, itself, still has the WIZARD keyword. I hope you're right, in that they don't count against the Wizard limit, but rulewise, it doesn't seem so IMO.

In Path to Glory Step 3 - Order of Battle, the Starting Order of Battle Limits has WIZARD units at a maximum limit of 1. Now we can get Arcane Waypoints as territories to get +1 WIZARDS, and eventually upgrade those to increase +3 instead of +1. But the issue still stands: early on in a campaign, the WIZARD limit of 1 is bad for Lumineth, as most unit champs and HEROES are WIZARDS. Am I missing something?
