Have any of you tested Annul main vs. Mana Leak. While it is conditional, you are almost assured of being able to use it on turn one.Â
I'd like to mention that in powered versions of Oath with Mana Leak, it is usually just as fast as Annul because you drop a blue source with a mox. The real gem of Annul lies in the fact that it is so inexpensive, so you can play an annul and a draw spell in the same turn.
