Tower tactics.

Golems stay at home – these creatures are rarely present in the army.

Now I'm ready for serious battles! So, the setup: master gremlins, definitely a supply wagon, obsidian gargoyles in the central slot, and mages in the far right slot. The remaining slots are occupied by master djinns (even if only one in each slot – they are not for combat!).
Next, the tactic: when it's our turn (and the probability that we won't go first is, unfortunately, quite high :( ) – the djinns, as the fastest, take turns casting 4 (!) useful spells on the gargoyles. That's it, this is no longer level 2, I guarantee you! These are BEASTS!!!!! :D
