Card idea

I've been a compulsive player and I want to contribute. So I came up with idea of tower. I call it Artillery. It will be Metropolis drop compatible with all types. Just in start it will have range of 4 fields. But it will be +1 range per 6 level. In addition it will have splash damage. Creeps in 3 range will revive 45% splash damage. Special: Auto Mode. 10% chance that cannon can get into auto mode and shoots up to 3 shots in random direction in whole map. +0.5% per level. Howz it. Thanxx. CBS
