[MtG] Mana Tithe

What I'd personally like to see as a change is that White gets 'Counter target spell unless its controller pays {1}' more often. Last time we saw it was Chancellor of the Annex as a bad rare. Blue should get Mana Leak effects less, and get more hard counters (but Blue's counters should generally be situational as a result of that). My opinion on it because, that way, White and Blue get individual-looking counters.
