New troops/building idea

Outpost - Defensive Building
TH 5 +1
TH 7 +1
TH 8 +1
TH 9 +1
-A clan castle like building, but you'll be the one to assign the troops inside, maybe 5-10 troop space

Programmable Tower - Defensive Building
A tower with modifiable property, in each level it can choose what to increase. Like damage, range or attack speed (but also gains a little of all property), you can also set each individual tower what troop they will be prioritized (with ranking).

Max of 3 towers, max level is 11 too, no graphical difference for the priority or the upgrades of each tower

Townhall Upgrade - Autorepair during battle

Maybe a small upgrade that gives the townhall the ability to repair a random building in its range during battle? number of simultaneous repairs will increase in each upgrade and also the range and amount of upgrades

Cloaks - A trap-like building that doesn't occupy space, it can swap the graphical image of two buildings (e.g. a collector and a tower). Once it receives certain amount of damage (like 200 the damage is also reflected on the building) it will reveal the real building behind it. If it was revealed, the trap must be rearmed.


Troops

Assassins - Almost same with barbarian on attributes, except that they are the last target of towers if there are many units present in the range.

Clowns - Colorful units that moves quickly, very small attack, above average health, but they move in a random direction in each attack. They're also prioritized by towers if there are many units present in the range.

General - A new hero that's available for early players, it has a passive ability to focus fire the attack of nearby allies to a certain structure. Recharges every 10 seconds.

Horse Archer - Fast moving units like hogriders, but they can't jump on walls. Instead, they will quickly attack a tower, then move to the next tower and attack it, circling all available towers in range or destroys a wall if there's nothing in range. So basically they're anti-AOE towers.

Trap Finder - A fast moving unit that can jump on walls. They cannot attack but they will roam the base especially the gaps inside walls to look for traps (they're also fast enough to dodge spring trap and bombs).
