Hi again.
Drain Power Wand was awesome for this strategy! I have revised my opinion of it, great with right support (Arcane Ring, Mana Crystals, Medallion, Harmonise, Mana Siphon).
Other great finds was Enfeeble and Force Hold. Along with Drain Essence and Pacifism, there is just too much to Dispel so some of them stick.
As for whether to go with a Thunderbolt Wand or Staff or Arcanum, I think packing both and making the decision based on your opponent is best. You certainly don't want to go melee against a fully equipped Warlock. I think it may be the same about Mana Leeches, used against creature-light builds where Suppression Orb and Mordok's Obelisk have litte value. Adaptability seems to be paramount. Just the impression I get. I may well be wrong.
In the end though, after an exhausting mentally draining game that seemed to be played in viscous slow motion, you can't help but think: "surely there are easier strategies to win with a wizard?"
Cerebral and fun are often different things. I far prefer luring the enemy into a well-executed Chain Lightning, with its exciting random dice rolls. That to me is a nice balance between non-random chess and an unpredictable dice game.
Mana denial works (in a 1 Core meta). But after 1 game, I'd only try it again on a hardened enthusiast who appreciates its finesse. Or if I really want to subject that opponent to a slow agonising game for some past wrongs!
Denial has always been a killjoy strategy. It's great that Mage Wars has a viable denial strategy (Nullify is just an easily-bypassed disruption) but it's not for every playgroup.
