Card Combo: Opal Idol + Corrosive Knife

[thesideburns]

Opal Idol = Everyone regenerates at the end of every battle.
Corrosive Knife = At end of battle, death to opponent who regenerated.

Pretty straightforward, and pretty deadly. The attacking creature merely needs to survive the battle (without losing the item) in order to win the land. So the combo should be incredibly useful against enemies with low ST and near-infinite HP, and a good answer to gaseous form, diamond armor, and shields that neutralize things.

The combo is vulnerable to item theft/destruction, and enemies with high strength. So what are the best creatures to abuse this combo with?

Nike or Succubus - prevent / lessen counterattack
Gremlin - destroys enemy item (if enemy's base ST isn't a concern)
Archbishop - prevents item theft/destr (if that's the biggest threat)
Vampire or Crimson Vine - initial attack buffs own HP
Centaur - recycles that precious Corrosive Knife

There are also a ton of creatures that neutralize or reflect different types of attacks, based on element or ST/HP stats. Pick the right neutralizing creature for the job at hand and you really can't lose unless the enemy uses a scroll or gremlin item on defense.

How about spells or territory abilities that could enhance or protect this combo?
Cramp - ST-20 to all creatures
Debility - ST0 to target creature
Tough Song - for offense
Mesozoic Song? - for offense?
Sinking Song - cast on defense
Paralyzer/Hyde - no counterattack or items

That's what I've got so far. Any thoughts on creatures/spells/strategies I've missed? Or ways in which this combo could complement a larger strategy/book?

Perhaps with everyone regenerating, this combo could be well-complemented by some WallTransform/Medusa/Cockatrice/BatteringRam/AcidRain action. I guess one benefit of using these two combos in a single book is that you don't really need "offensive creatures" with super-high ST or critical hit attack abilities; your high-HP(low-ST) creatures are now equally suited for offense or defense.

I've used this combo in a book I ran a long time ago based on small, cheap creatures. Mesozoic song was one of the spells I used to run the Corrosive Knife. It's good because it also combos with Saint if you cast it on the enemy.

You neglected a couple of creatures that would do well with this combo and they are Succubus, and walls. Succubus is good because a successful hit will deplete the enemy's base ST. She, unfortunately, suffers from the same problem as others, like Nike or Archbishop, suffer from in that she kills herself so a Counter Amulet can stop your combo. I believe all walls can use weapons and they not only have decent HP, but generally no ST so they defeat Counter Amulet. You can attack with walls by using Intrusion or Chariot.

I actually strongly considered putting Corrosive Knife into my Team Leshy book, because intruding with Leshy and getting a free level appealed to me. It's probably one of the best places to use it since Opal Idol is such a key element to the book combo and intruding with Leshy is a legit strategy with it. However, I feel that there are better ways to use the two or three cards one would allot to Corrosive Knife in the interest of speed.

I'm in the middle of creating about 5 books right now that are based on idol usage and this is one of them. My problem is that I need to get multiples of quite a few cards before I can test them out.
