How do you kill a summoned phoenix?

Guys, tell me, a newbie, what to use to kill this beast?! Today I was playing against a Necromancer, and the game dragged on a bit, and then we met in an open field. First, this Necromancer summons a Phoenix, which takes down 2 of my Angels with a single attack (I had 5 in total). It deals massive damage, has excellent armor, and a ton of health. Honestly, this Phoenix creates a clear imbalance in summoning magic :(. Need help...

If you're playing as Necromancers, the Death Knights have "Death Grip." If you're playing as Inferno, the Cave Lords have the "Slicing Blade" ability.
If you're playing as Mages, the hero will gain the "Banish" ability when leveling up their summoning magic. Although it's available to heroes of all factions except Barbarians.
If you're playing as Dwarves, I would attack them with Berserkers in abundance, but only if there are many of them.
But I see you're playing as Humans, so attack them with Royal Griffons from your reserves, then with Archers, and then overwhelm them with Paladins... But in general, you should still try to level up summoning magic... like Banish...
