Discussion about Sylvan (Wood Elves).

Yes, that's true, but you have to agree that the enemy is forced to spend an entire turn on some ridiculous spell that also harms its own army.

And regarding "Phantom," I was surprised to discover that the cloned creature has the original characteristics of the spell's target. For example, if you clone an archangel that has already cast resurrection, the phantom can also resurrect. And considering the phantom's unreduced initiative, it will be able to resurrect someone before it is defeated. And so on, endlessly.
