New item- Tomla's Lance

Right now, enchanters like lulu janna and support karma are pretty big in the support meta, and make adc's extremely hard to deal with when they are constantly shielded by 2 or more supports, these shields also give them huge bonuses like life sap, movement speed, and even straight ad. I propose to create an item that allows you to reduce the power of shields when attacking.

Tomla's Lance -800 g -15 ad

unique passive: tomla's lance pierces through even the thickest of shields, causing double damage to shields.

Here is where the item really shines, Tomla's Lance will be an alternative to executioners calling, but instead of building into a new item, it will be interchangeable with executioners calling in the only thing that changes is the unique passive
