Chromatic Collision

nonesense really but I was thinking of Magic the Gathering cards and if I were to make one, as multi-colored cards are my favorite...I'd make something like this:
---
Chromatic Collision - 1WUBRG

-pic above-

Enchantment - Aura - Rare
Upkeep: 1
W: Prevent 1 damage that would be dealt to target creature or player
U: Tap target creature
B: Target creature gets -1/-1 until end of turn
R: Deal 1 damage to target creature
G: Target creature gets +1/+1 until end of turn

Sacrifice Chromatic Collision, you may play any card in your hand as long as it's a mulit-colored card with a casting cost below 6

If Chromatic Collision is put into a graveyard from play, you lose half your life.

Mages that tried to harness all forms of mana became the greatest of all planeswalkers yet those who failed to control that power, became the greatest of all failures

note: this is not a real Magic the Gathering and Magic the Gathering is a trademark of Wizards of the Coast which is a subsidiary of Hasbro (I think)
