New suggestion: Spell Trap For Defender

[iEynn]

Mainly used in clan war. At the preparation Day, we can choose one spell to a place. If the attacker's force trigger the trap, the ring of spell will acting the building. example, healing spell heal the building's hitpoint; rage spell make the defense building stronger, high speed to fire; lighting spell will hurt the attacker's force; the jump spell will spring the force some grid distance.

Is this funny and practical?

Sounds more like a way to "trap" de zappers

it's just need only one grid.
