So these are a couple of ideas that I would love to see in the game. Anyways. Let's start with the troops.
Name of Troop Air Goblin
Training Cost: 10 Dark Elixir
Training Time: 30 Seconds
Housing Space: 2
Damage per second: 18 (28 On Resources)
Hit Points: 40
Movement Speed: 29
Description: So you need loot but your tired of ground goblin attacks? Introducking the Air Goblin, powered by Dark Elixir this goblins flies threw the air collecting loot with his maginet, but beware as its balloon will pop if he gets shot down by Air Defense.
Reference Art: 
Special: It acts like a normal goblin but flies. But if it gets shot down by air defense it falls down and acts like a regular goblin would.
Great For: Bases with no air defense (Archer Towers don't count)
--------------------------------------------------------------------------------------------------
Name of Troop: Cannon Skeleton
Training Cost: 1500 Elixir (E)

Now that the troops are out of the way, Lemme intorduce a new obstacle, The Dark Elixir Stone!

This has the spawn rate of 2 every 8 hours. It will give you 50-150 DE. To remove the obsacle it'll cost 5,000 Elixir.
This is honestly the best thing ever, Not too OP not unbalanced just. Pure Perfection.

Now, this is my favorate. This Is what I like to call the villager outpost. Heres a picture:
This building is almost like a all in one building. Heres what it does:
- Now, when you get attacked, Villagers and builders will run into this instead of the Townhall.
- This building will hold 10,000 of your gold
- Act as a archer tower
- Allow you to trade troops
So lemme explain the troop trading. So now Lets say someone in your clan wants to do a trade with you. In the clan chat they tap your name and click this new button that says "Trade". Whoeveers trade button you click will get a trade request in their inbox. Click yes or no. If you click yes what happens is you can trade every troop withen the tier. So if you have a level 1 Outpost you can trade tier 1 troops.
TIER 1: Barbs, Archers, Gobs
TIER 2: Giant, wall breakers, balloons, wizards
TIER 3: heale, dragons, pekkas
DE TROOPS: Minions, Hogs, Vlaks, Golems, witches
Level 2 outpost is tier 2 troops. Level 3 is tier 3 and level 4 is dark troops. So if you ask a top player in your clan for a pekka, you can only get it traded to you if you got a level 3 Outpost. Also you can only trade within your tier. So level 1 Villager Outpots can only get and give Tier 1 troops. so its not OP. You want to trade a pekka? Unlock the tier 3 Building! Anyways Here Are Its stats.
Level 1
Hitpoints: 600
To Build/Upgrade: 300,000 Gold
Tier Trading: 1
Unlocked: TH6
Time To Build: 8 Hours
Level 2
