MtG Lore Army Combinations

Trying to create preset armies to run scenarios based on the Magic card game story.  I've tried to keep them balanced but the main focus is on flavor.  Does anyone see any obvious imbalances?

Assuming you only have 1 of each set:
Gideon Jura                             - Rhox Veterans + Avacynian Inquisitors (525)
Nahiri, Fury in Stone                 - Kor Hookmasters + Goblin Javelineers/Kor Aeronaut Captain (505)
Kiora, the Rising Tide                - Merfolk Roilmage + Eldrazi Ruiner (595)
Ob Nixilis                                - Skirsdag Cultists + Eldrazi Scions (490)
Sorin of the Eternal Thirst         - Avacyn + Malakir Bloodchasers (545)
Arlinn Kord, Goldnight Outcast    - Kessig Rangers + Mad Prophet (505)

Nissa Revane                           - Elf Rangers + Pummelroot Elementals/Path Wardens (~500)
Jace, Investigator                    - Necro-Alchemist + Lantern Geists (500)
Jace Beleren                            - Illusionary Projections + Layline Phantoms (500)
Chandra Nalaar                        - Flamewing Phoenixes + Blazing Firecats (500)
Liliana Vess                             - Restless Zombies + Blighted Reavers/Ghoul Vanguard (~500)
