Loonian has been good, but I'm beginning to re-appreciate furs in Crystal II. Assuming no inferno towers (which I try to avoid) there's really not a lot anything on the planet can do about 18-20 fur coats + 1 healing spell.
More info please...
I've only just started playing with this, but basically I was hitting next a lot with loonian armies because most layouts in this range have everything in the center, including the anti-air turrets. Maybe I'm just not very good at loonian, but for me, it's always kinda awkward getting to the middle. I deploy loonian in one or two sweeping lines.
With a fur coat ground army, you can direct your troops to the center easier IMO. There are always defensive buildings in the middle which fur coats will go to, all you have to do is clear out any defensive buildings that might pull them into an orbit, and clear a path with WB's.
And really, if you've ever seen a large group of fur coats under a heal spell, you know that they basically walk around like nothing is hitting them at all. They look nearly invincible. I send the giants in, use archers to clear out defensive buildings on the outside, send in some WB's and drop the wizards. I generally hold a large number of archers in reserve until the giants have done a lot of damage in the center, then send archers in to clean up.
I'm playing with numbers still, but generally 16-20 giants, 12-16 WB's, 8 wiz, rest archers has been my plan. It's expensive - easily more than 150k de a pop whereas I think 28 skulls is like 130k, but it has the benefit of not having to spend DE on minions. I bring 40 minions with my loonian, which is what, 400 DE? The Crystal II bonus is only 200.
So if you have some elixir laying around and are focusing on DE, I just think it's a little easier to control than loonian. And again, I could just be bad at loonian, but it just seems like I find a ton of layouts with four anti-airs in the middle and x-bows up. I immediately pass on those. I might be able to get it done burning all my spells, but I'd rather not have to try.
ETA: It also alleviates the thing I have most about loonian, which is finding an abandoned base with full collectors and having to use minions, and sometimes loons too to tank, to empty them. This is not very common in Crystal compared to Gold, but does happen, and everytime it does, it's annoying to not have archers available to take them down.
