Here are more ideas from me. I hope interesting ones here are... What are you thinking about it? Any suggestions?
Shaman -- Creature -- 1/2 -- Costs???
mysticism: Pay X+2 Quanta to destroy the target Weapon or Shield
Destructive Flames -- Spell -- Costs???
Destroy the target non Pillar Permanent and get damage, equal to the casting costs of the permanent.
Alternately destroy the target non Pillar Permanent and deal damage, equal to the casting costs of the permanent.
Fighting spirit -- Spell -- Costs???
Sacrifice one of your own creatures and deal spelldamage equal to the creatures attack.
Cursed Stones -- Permanent -- Costst???
Your opponent (or maybe both players) get 1 damage every turn for every pillar he (or they) control, diveded by 2.
Fire Imp -- Creature -- Attack/Health -- Costs???
When the Fire Imp comes into play he deals 2 damge to a target creature.
Time Wizard -- Creature -- 1/2 -- Costs???
Equalization: If you have less HP than your opponent pay (x) to deal 3 damge to your opponent.
