Now - about walls...

...I love 'em. To me, no deck is complete without one.

To date there are 15 different Red walls available. Several do damage wile defending (which means that they can be flung...more on that later) but I'm old-fashioned, and stick to what I've had since the beginning:

Wall of Stone.

It doesn't do a lick of damage, but can take 8 points of damage before falling. This is the toughest of the bunch. There's Wall of Granite and Wall of Earth, but they're 0/7 and 0/6 respectively.

Now, combine this with Firebreathing (which I have) and this bad boy could do some serious damage (as well as being flung...more on that later).
