Or even worse, having the Wand setup, Wan defenses setup, and being forced to do something other than what you have bound to the wand. You are then forced to either do that "something else" or pay the three mana and swap out the spell bound to that wand with that "something else" and end up for practical purposes with only one action (quick or full). Don't say Battleforge as that is during the Deployment Phase, what I am talking about happens after during the Action phases. Get caught like that a couple of times and you will start thinking like the rest of us: Wand - meh.
I agree this does happen sometimes. But (in my opinion), I think it's better to be able to swap the bound spell and do what you need to do, and always have that option available, rather than "try to guess which spells I'll need and in which quantity I'll need them, be wrong, and not be able to deal with something."
Without a wand - Do I put 3, 4, or 6 Dispels in my Book? 6 Dispels for a non-Arcane Mage would be 12 points worth of spells! (that's a full 10% of my allotment.) And what if my opponent isn't using enchantmens...then that was a waist. What if he has more than 6 enchantments in his book....everything beyond 6, I now have no way to deal with. Same thing for Equipment. Do I commit another 10% of my allocation of spells to deal with 6 pieces of equipment I may want to dissolve. What if he has more than 6, now I need "Explodes" or "Steal equipment (based on the cost of the items I'll have to deal with...which I don't know when I'm constructing my books). How much of my book do I commit to this? I have no way of knowing how much I'll need, and if I don't bring enough, then I can't deal with problem items my opponent may cast after I'm out of Dissolves.
With the wand life is much simpler - ONE wand and ONE Dispel gets rid of as many Enchantments as I need to get rid of. That's 6 total points of my allocation that's 5% of my build total. So it cost me 5% instead of 10% and has unlimited uses. (much more efficient). AND if I can deal with both objects and enchantments with ONE wand ONE Dispell, and ONE Dissolve all for 8 spell points - That's 7.5% of my build total, and I'm dealing with as many of BOTH Equipment and Enchantments. But wait, there's more!
What if my opponent throws an Earth Elemental, Iron Golum or some other big SLOW creature, with One Force Push I can now keep that elemental away from my Mage and Spawning point (or whatever I want to keep him away from), until my ranged attackers can whittle him down. And that's only another 2 points. So now I can deal with ALL Enchantments, ALL Equipment and cast Push as much as I need to for still under the 10% of my Book total someone without a wand would need to commit to just deal with 6 Enchantments.
But wait...there's more want to add an unlimited amount of healing? add ONE Heal card, unlimited Teleportation, ONE Teleport.... Never run out of any of the creatures you cast .... One Resurrection. The price of setting up some wand protection, and the price of having to pay 3 mana and a quick cast action to swap spells I think is an excellent value in all of the diversity it affords me.
I don't know about you guys, but I'm never satisfied with the contents of my spell book. Once I reach 120 points there are still a bunch of cards I want to put in my book that I might need. And I'm someone who uses wands in almost every book I build. If I didn't have the wands, I'd have to guess in the dark as to how much of many things I'll need, risk being wrong and come up against something I can't deal with.....and I'll have less room in my spell book to put the things I think I'll need for offense in there.
You guys who end games in 7-10 turns....when you build your spell books you must get about 60 points in and go...."That's it", that's all I'll need to win. I'll just put 60 points worth of utility spells in here "Just in case". Is that the way it works for you? Not me - When I build books, I try to think of what I'll need. "What if my opponent does this?" do I have the spells to deal with that, what if he's doing this? Then I'll need these spells too... I pretty much never get to a point where I think "I have everything I'll need in my spellbook" before I hit 120 points....heck, even at 120 points, there are always a handful of cards I need to guess and make compromises on due to the limit. Without wands it would be horrible, I'd just have to build decks that I know have glaring weaknesses.
