elemental summoning tactics

Also, if we talk about classic strategies, summoning elementals works well in combination with resurrection. For example, you can take Utopia, bringing only 6 units of some kind into battle – spearmen, goblins, it doesn't matter. In the first turn, dragons eliminate 5 units, we summon elementals, then again and again, until we win the battle, and at the end of the battle, we resurrect one of the units, and the battle is won with the loss of only 5 units. The only essential condition is that the hero's power must be high enough to summon many elementals. There are many battles that can be won this way; you just need a lot of mana and a good spell.
