After Land and Air Now it's Time for Water

We have walls to guard our villages. Now it is time for Trenches, the most common defense in a medieval castle.
Water filled Trenches have the following scopes :

• Slow down Golems and Pekka.
• New Spells - Drought (to dry the trench) and Tsunami (to deal damage to buildings in a given radius with a wave of water)
• New Defense - Water Jet (Spray of water harming the lava hounds)
• New Traps - Spikes and Quicksand

• Build Hydro Barracks and Aqua Camp for Water Troops.
• New Resource - Pearls
• New Buildings - Pearl Collector and Storage
• Troop Suggestions :

1. Piranha (like Barbarians or Minions , deal small Damage )
2. Shark Surfer ( like Giants or Hog Riders , targets Defense troops , the Surfer jumps down the shark to move on land )
3. Pirates (like Wizards or Archers , Ranged troops )
4. Mermaid (lures Clan Castle troops )
5. Dino Shark ( like the Dragons , can move on land )
6. Kraken (like PEKKA or Lava Hounds, absorbs damage and attack defense buildings , can move on land )

• New Hero - Charybdis (spawns Whirlpools , which deal damage and hide the Hero for sometime)

Good idea but supercell won't spend that much time changing it they will look to improve the game in other places
