Denial, new Summoner Spell

Keeping it short, Denial would be a targetable silence with equal or slightly greater range than Ignite. While the silence could increase upon key levels 6-11-16, currently I'd like to keep it a 1-1.25 seconds long to avoid criticism. Suggesting this to fill the gap between popular and uncommon Summoner spells, as it could be popular among initiators or assassins, however, they would have to sacrifice either an Ignite or a Flash to be given the small window that "Denial" would allow them to jump on the target.

There's a lack of Summoner spells in general, not just popularity among the eleven currently on Summoner's Rift, or the Mark/Dash on Abyss, Garrison on Dominion, etc. While there aren't a lot to pick from, it's usually kind of like picking an apple off of an apple tree or kicking the tree as hard as you can barefoot.

The VFX would most likely be kind of similar to Nocturne's Bind/Fear in a way? Shadowy lockdown I suppose.

Here's the Summoner Spell icon.

Edit 1: As a side thought, instead of a flat out silence, it could deny usage of basic abilities, but allow Summoner spells and Item actives to be triggered.
