After much consideration I have decided to remove all references to Desert Terrain on Champion's Odyssey cards. There are two reasons for this. First, after reviewing cards from the base sets like Desert Giant, who gets a Dry Heaps bonus, and reading the Guide to the Mid Realms, it is apparent that Dry Heaps was to be synonymous with desert. Also, I didn't like the fact that it penalized one group of creatures with a bonus (Rivers and Lakes) without a balancing penalty for other types (such as Dry Heaps creatures trying to swim in Rivers and Lakes while fighting!).
All Champion's Odyssey Terrain that referred to Desert will either have the Desert removed, or replaced with Dry Heaps. Creatures that had Desert bonuses will have those bonuses replaced with either Valley of the Gods or The High Steppes, which also serves to tie them to the Champion's Odyssey set more closely.
New versions of these affected cards will be posted soon.
Also, stay tuned for news either later today or tomorrow. There's a reason why this blog has been quiet (I promise I have been working hard on content!)...
