Considering the amount of time that has past, most if not all of this has probably been changed, but I felt like digging it up...

How about a hunter's guild(think most dangerous game here). You can buy all sorts of different animals in a city but you have to trade x number of promos(hunting trophy promo, gained when a recon unit built in a city with the hunter's guild
in it kills a barbarian or animal unit, the number of "hunting trophies" gained varies with strength difference and number of promos the killed unit has) to buy them. Units can trade in these promos for various traps as well:
bear trap: +40% defense vs bear, 2ht
caltrops: removed when used, first unit that moves into square have a 60% chance to loose all mp. 1ht
mantraps: +50% defense vs barbarians, 3 ht
pitfall: removed when used, enemy units that move into the space have a 30% to fall in, losing all movement and granting attackers 1-2 first strikes while in that square. 2ht
scorpion venom: unit attacked has +1 movement cost. 4ht
spider venom: unit attacked is damaged 1-5% if it survives combat. 4ht
In addition animal units can be upgraded to next str level like wild animals by expending ht promos: first upgrade=3ht, second=6ht, third=12ht(it caps at 12ht, and you can double its base strength via this method). This requires a beast rearer in city, a building that can only be built in cities with hunter's guild in it. It can train animal units up to 10xp.
Provides a number of unique artifacts that can be randomly gained when you kill certain units:
Live for the kill: A bow that can be gained after a unit
kills 50 or more units in combat. +70% offensive strength, immune to fear
Trophy armor: kill one of each animal. the unit causes fear in tiles it attacks
Hunter's Trophy Spear:gained from collecting hunter's trophy promo 25 times with a single unit, doubles the amount of ht promos gained per kill.
All of these promos can be gained by ONE unit per game. Units
can use the capture prey ability to capture other civs units in neutral or allied territory.
In neutral territory, there is a 40% chance of success(modified by level difference).
In owned territory there is a 60% chance of success, but also a 60% chance of suffering a diplo penalty with the unit owner's civ. If you fail to capture the unit in any case, the unit's owner will declare war on you. This ability can only be used once for every 10 levels the unit has. If it suceeds the captured unit is turned into a barb, moved 5 tiles away in a random direction, gains the prey promo(-30% defense vs units huntsman promo, grants double experience and ht promos to huntsman unit), and if it returns to its civ's borders it regains its nationality and you get a diplo hit with the unit's owner.
Requires tracking and poisons, can only be discovered by a level +8 recon unit, with the hero promo. The unit is sacrificed to found the hunter's guild.(sorry didn't feel like going all the way to the guild ideas thread to comment
)
I think it might be a bit more worthwhile to get.
