Offtopic » An effect that could save Warlock

Hi,

This could really help Warlock use it's self harming demons and spells.Obviously this card would need a high cost, or a condition (all have to be unique cards?). Or maybe put the effect on an easy to remove (Legendary) minion. Or maybe it should be a spell that only counts for one turn.It's an idea that could bring back a lot of 'forgotten' Warlock cards out there?

Please help.

I didn't find the right solution from the Internet.
