You can use Temple Defender instead, of course, but Grimnir is cuter.

Ah, so he's purely a ward unit? Well, Temple Defender is great, especially against humans and Sylvan. I always chuckle a bit when I place him and the enemy's slot is occupied by a 1-attack unit.

Temple Defender is great.

However, this might not apply to Storm, as the priorities there might be different.
