Which level 7 creature is the best, and why?

In my opinion, this shouldn't even be up for debate because it's an Archangel. It has the highest attack and defense, both at 30, and deals powerful, consistent damage of 50. It also has the highest speed, 18 (only surpassed by the Phoenix at 19). Furthermore, I read that 3DO made it a unique unit; when attacking or defending, its skills are artificially increased by 30%! Plus, it can resurrect allies and has high morale. In a 1-on-1 battle (I've done tests), it can defeat 3 Phoenixes and 2 Bone Dragons. The Archangel is the most important strategic unit in the castle because it does half the work for them. And it doesn't care about Titans or Dragons. In close combat, it can only lose to a Monster in 30% of cases. But all of the above gives it undeniable superiority!
