I CAST....!

I CAST DELETE×3. The nuke and both antimissiles are deleted.

I CAST…COUNTER SPELL (not to be confused with counterspell)to summon a counter over gooses head 

I CAST TABLE SPELL! A table collides with the counter midair.

WITH MY BONUS ACTION, I CAST... ATTAAAAAAAAAAAAACK! Instantly, myself and every creature allied to me attack all at once, dealing 1633 COMBO damage that bypasses all forms of protection.

I CAST…CHAIR SPELL the chair collides with the table 

I CAST... AWAKEN! All three objects in the clash are Awakened and being fighting.

WITH MY BONUS ACTION, I CAST... NOCLIPP! You fall into your ground as if it wasn't there and get sent to the Backrooms. (The version from the wiki.    I won't specify which because I literally can't)  Good luck finding a level with an exit to that place!

I CAST… JUJUTSU SORCERY,the three now awakened objects have access to cursed energy 

It has been previously established that I cannot be trapped in the backrooms

Oh yeah, well how about THIS? I use plane shift to send you to the Decay canon and teleport you directly into the Decay itself.

WITH MY BONUS ACTION, I CAST... NARRATION!

The battle rages on well into the night. Remember that Faceling from earlier? Well the magical overflow from the spell you just casted gave him access to cursed energy as well. A flash of darkness shatters the chair and a pulse of lapis absorbs the counter. We have won the battle.

I CAST…THE TABBBBLLLLLEEEEEE,the table proceeds to land 99999999999 consecutive black flashes before ending the faceling with a domain expansion 

Btw you caaaaannntttt escape mmmmeeeeeeeee

(You get hit by 99999999999 consecutive black flashes because the table is on my side since I summoned it)

I CAST... THE WRETCHED CYCLE! You immediately begin undergoing the Wretched Cycle (like the Backrooms phenomena) at an accelerated pace.
