Besides the names, trials also have some special rules that are often not mentioned in their descriptions:
You or your opponent may be given some starting resources. This is almost never mentioned.
This can make a big difference in your strategy, as you will be given a certain number of each resource in your deck, so using a multi-resource deck can give you a large advantage.
Some units may have modified stats. This is sometimes mentioned.
Some enemy units may not be targetable by spells, enchantments, or abilities. (I did not take note of this when collecting the information, sorry.)
