We are pushing the hit-and-run strategy of the Academy.

If you deploy Black Dragons, it will be pointless... I won't even bother with Armageddon! You can just shoot them down with a single spell! Of course, not all of them, but the losses won't be equal...

Let me explain in detail. With 6 stacks of Furies and 1 Black Dragon, he attacked a Mage (let's say it's an Oracle with Keen Mind) with 6 Tier 2 units and one large stack. So, the battle: Furies go first and destroy the Tier 2 units (Razazak doesn't have Defense to the Last after all). Then, the Mage's turn, he casts either a single direct attack on the Black Dragon, or the Black Dragon destroys the remaining stack (the Mage loses his hero), or it takes out a significant portion of it. After that, the Mage can't attack anymore, otherwise, it's death. In total: the Mage destroyed the stacks of Furies, lost almost all of his Golems, and attacked the Black Dragon once, probably killing one. And that's still
lucky; he could have just fled (if he realized that the stack of Golems wasn't strong enough) and even lost his hero, for example, due to the Black Dragon's Luck.
