Question

[Shadowglyph]

Okay, we have

FlashFreeze - Counter Target Green or Red Spell
Deathmark - Destroy Target Green or White Creature
Cyroclasm - Destroy Target Planes or Island, Deal 3 damage to the Controller
Luminescence - Prevent all Damage Red/Black Sources deal

and does anyone know what the green one is?

 

[Modus Pwnens]

Wallop - Destroy target blue or black creature with flying.
or possibly:
Karplusan Strider - Karplusan Strider can't be the target of blue or black spells.
Snakepit - Whenever an opponent plays a blue or black spell, you may put a 1/1 green Snake creature token into play.

Plenty of options
