The real test for your angel would have been that group of heavy infantry (150; the type won't matter since they can't hurt the Angel) backed up by few High Inquisitors, one of them a prophet. Fanaticism, Smites and Words of Power help a little. Add 150 Crossbowmen. Add two Grand Masters, with randoms in Astral and Fire. One casts Light of the Northern Star, then Antimagic, the other casts Flaming Arrows, then Fire Fend. Then add 16 Witch Hunters, half casting Phoenix Power and spamming Fire spells, the other half spamming Paralyze (which they can cast thanks to Light of the Northern Star). If the Angel is immune to fire (as he should be when going against Marignon), the Witch Hunters would spam Blindness instead.

You had Conjuration 7, Construction 4 or 6 for the Angel. The above combination would require Enchantment 4 for Flaming Arrows/Antimagic, Enchantment 5 for Fire Fend, Thaumaturgy 4 for Paralyze, Conjuration 4 for Light of the Northern Star and either Evocation or Alteration. In a real game, Marignon would probably two of the four schools at the levels needed for this.
