Even though Wong was my cheapest run (besides GM portion), I would recommend more revives since this is your first Necro run. Especially since your units are really low too. Wong SHOULD be able to solo almost all of the fight, but since you haven't done it before, you will probably need more imo. If you don't mind potentially being stuck and having to grind units in Arran though, you're more than set (and in fact, if your skill is good, you're set right now).Also, the GM reverse control phases mess people up on their first run through.
