[PvK]

Kydnides are great. Also my Oceania has managed to get (I think more or less as an eventual result of native casters and forging boost items): Naiads, death Naiads, Vine Men & Ogres & Kings, Ether Warriors, Firbolg, Spectres, Faerie Queens, Water & Air (& Earth via pretender) elemental royalty, Djinn... and even without the unique summons I could have several other types but I'm doing fine with these. Wave Warriors and Kydnides make a good army center at least against general foes who don't have too much artillery - human opponents could hurt them easier than the AI. I think it's a bit challenging because one needs to get more creative and mix/match with indies, expensive summons, etc.
