or make the range 1-1

Fog bank right in front, or use the assorted counter cards exp. earthquake

this one

When I play it, I place wall of earth on the opponents side down the middle and extend it. Then I place akiros hammer behind the open border.
If they place any wall but fog bank, they block their way in. I usually have talos charging up by then, and the longer they wait, the worse for them it gets because I have a deck packed with power creatures. I give standard bearer to thorg and I run around with 11 dice quick attacks (harshfoge hammer, ability, gauntlets, bear strength, power strike on helm of command, standard bearer). If they block it off, they make their situation get worst as I bring out iron golem, sir corazan, grimson and boltstorm.

some spellbooks only have 2 walls, and most have a max of 4. If you have 2, and you use 1, there is no possible way of blocking yourself in in case of emergency. Also, asume the warlord is on the attack, they do that to the hammer, the warlord retreats the opponent follows, and they get blasted if they are swarm type and forget.
 It could also draw the opponent to you earlier than they want, even if it is just 2 zones, you move and place force hold or block their way back with your walls, they are trapped. This card is not all purpose, dont get me wrong, I only think it is good vs turtle, swarm and altar of sculls.
Nice balista

Most people think akiros hammer is terrible, and a waste. Here are some uses that might change those peoples minds:
1. really good vs annoying wiz tower/any annoying conjuration: Exp: temple of light, vine tree, walls, moktari tree, etc.
2. Turtling is destroyed by the area affect attack.
3. large hit points.
4. When more siege weapons come, the worth will increase.
5. 2-3 range
6. Standard conjuration range
7. Can be annoying and draw attention
8. If you need time and the opponent turtles, this applies pressure and lets you build up

This by no means is a worthless card, and it will become more valuable  the more conjurations come out.
One common complaint: the 8 die attack can't target creatures. My answer: Its a trebuchet, and those aren't known for accuracy, but range. While a trebuchet can hit a building, it can't hit a single target.
My one complaint/critique is that it doesn't have the indirect trait on the aoe attack. please place arguments if you have them.

I've heard people talk about a ballista, could someone send the link. I love siege weapons, and have more ideas for them.

earthquake on obelisk, bind dispel on mage wand, nullifies and reverse magic on myself (1 at a time to avoid purge magic). quicsand either forces a teleport witch would be better used when you are being force held, or wastes a creatures turn (possibly destroys it)
