I wish Far Sight was the exact same card it is now, but with 2s instead (costs 2, reduces cost by 2). This would make it a lot more includeable as an alternate to our turn 2 totem plays, and also reduce the RNG disadvantage of when you would currently draw a 1 or 2 cost spell, since you'd only be hoping to avoid 1 costs as what it draws. Right now, our mana curve when running overload cards requires too many 1 and 2 costs that the chance of one them being drawn is too high, especially when you count in all our cheap cost (almost required) spells.
Think about it - turn 2 Far Sight, turn 3 Feral Spirits, turn 4 could actually be a full turn 4 depending what you drew, completely offsetting the overload from FS! That would be great! And all the chances to coin Far Sight for a hopeful 4 drop on turn 2. :D
