Also transfusion is almost an auto x2, as long as you are running Flagellum. Think about it, you move up to a unit that has 4 ap held, with any unit, you only have 4 ap left, you use transfusion on the enemy unit, now not only can you double hit, but your flagellums also gain 4 ap, possibly allowing another hit. Either way you are creating 8 free ap (4 if only one flagellum is out) makong is a 16 ap swing, off of a 30 nora spell. -4 to the defending player, +12 to the attacking player. I've used this on multiple occasions and transfusion basically acts as 3 quickens in so many cases.
Ok, so update on Vex Core Pram. I've been derping for an unreasonable amount of time. Realized a few days ago that I can use it on my champs, and they won't take damage. The target only takes damage if it is an enemy unit. An since the Defense is only removed for 1 turn, you've nothing to fear about using it on your champs. This spell has been stupidly effective with Sandstalker Lords in my Sand bg, as well as with a few other champs namely Centurion. Fight in Formation make it even easier if your able to plan a few rounds ahead. Been running it as a 1x auto recently, and it's not failed me. I suggest you put a little more effort into this rune if your able. It'll pay off.
