I don't think the cost should be lowered, because look at the last thing I wrote
Sounds intresting, but i have 3 questions
Can you use this on only your own creatures and perms?
and if the ability requires targeting eg snipe would u choose who it snipes?
and a lobotmized perm? how would it work
1. you can use it on any creatures or permanents, even your opponent's
2. the player who played the card gets to pick the target
3. well, for perms that have an ability that you activate, like sniper for OE or Lobotomizer, it would remove that, but for things like ice shield, the "attacking creatures might freeze" will be removed, while keeping the "damage is reduced by one", or for discord, the quanta scrambling would be removed, while keeping the damage.
also, one little detail I forgot is that the ability used still costs quanta, but if the player who owns the creature that used the ability doesn't have enough quanta for that ability, it is free.
