Wizard battle!

Welcome to the Wizard battle! This is a forum game where any trick goes!
Basically you just have to name the spell you use to defeat or counter the previous spell caster in some way. It can be from a ward or magic missile all the way to a portal gate or meteor storm! All basic forum rules apply. You are allowed to gloat, but don't be unpleasant about it.

I'll go first.
Summon lesser beast.

 

Summons portal right under the beast.

 

I cast portal lock!

 

I summon magic key to open the lock!

 

I cast heat the metal to make you drop the key!

 

I summon a water elemental, quickly cooling the key and attacking the caster!

 

I summon a demon to combat the elemental.

 

I recite a purification tome, destroying the demon and purifying the area.

 

I use the hallowed energies to cast ray of holy light!

 

I summon magic mirror to send the light back at you!

 

I cast spell shatter to destroy the mirror!

 

Cast portal to summon army, distracting the caster

 

I cast heat metal, to burn the army in their armour!

 

I cast spell ward, protecting my army!

 

I summon a ward eater to destroy the ward!

 

I cast a portal to my pocket dimension under the ward eater, to store for later.

 

I cast magic missile at you!

 

I cast anti magic shield on myself!

 

I summon a dagger and throw it at you!

 

I teleport away!
