Zone Equipment (an equipment placed on the arena) (something I just thought up)
Quick cast
Mana cost: 12
Target: "Zone" (0-2)
School: Air (5)
Whenever a player cast an air spell, all creatures on the zone with Lightning Rod takes 2 damage. When a mage is next to Lightning Rod, they may spend one full action to transfer lightning rod 1 zone away.

Note: Here, I tried something new. I didn't want to make it a conjuration/enchantment because it IS made of metal, and I think getting rid of it with cards like dissolve makes more sense than using dispel . Hope you guys like it. Items like these would definitely increase the amount of chaos in the arena.
