He makes the Headless Horseman useless. He reduces the Living Wall to a vanilla joke. He can even mess with Gib Lhadsemlo. When it comes to monsters, Kronos is definitely top dog.
Honorable Mention - Living Scroll (3rd Edition chase, 408/420)
Here we go with our first-ever honorable mention! The Living Scroll is one of the best defensive champions in the game. Wait until a hero or cleric attacks your formation and BAM! slap this baby down and watch your opponent's champion go straight to the discard pile. Pick up a spoils and smile. When attacking, it's not nearly as good, because your opponent will most likely have other champion types at his disposal. If one is a wizard or monster, the Scroll needn't bother attacking at all. In rare cases, however, the Living Scroll can actually be a decent attacker, gaining you a quick spoils and razing a realm unopposed if your opponent has only heroes and/or clerics in his pool and hand. Nice champion, not quite good enough to make the top 3 monster list, but good enough for an honorable mention.
Next time: Going psycho!
