Which castle is advantageous against the Stronghold?

On this contested island, the main goal is to quickly and efficiently eliminate 10-15 Phoenixes, which guard the most valuable resources. I usually play as a Barbarian on this map, primarily using Krag. He can destroy the Phoenixes with minimal losses by the 3rd week, but I usually don't rush it (I clear my own peninsula first) and attack the Phoenixes around the 4th week. Therefore, the opponent's task is to develop enough to eliminate 10-15 Phoenixes and then face the Barbarian with a 4-week troop increase (which is quite significant, considering dwellings and "troop gathering"). The Necromancer has little chance if he doesn't have "Dominate" or "Berserk" in his magic. The Warlock must play very carefully with the Phoenixes; otherwise, with a small army, his fate will be a "hit-and-run" tactic. The Warlock probably has the hardest time on this map; invisibility won't help against Phoenixes, as they are very fast. Elves and Humans, with their hordes of archers, can easily destroy Phoenixes with minimal losses, and they are very effective against Orcs (my most hated opponents). Wizards, thanks to summoning elementals, make Phoenixes practically indestructible; they need good development and useful magic artifacts. I can't say anything about Demons, as I haven't encountered them. General conclusion: If you can play Wizards well, play as them; Humans are second best (the downside is that the map is very resource-poor); the Necromancer relies on luck (he needs Berserk and Dominate in his magic)
