Channeling Curse

[Iudicium86]

So while playing with a friend recently, It occurred to me that while there's Harmonize (+1 channeling for anything with channeling trait) could we ever see basically a curse to cause -1 Channeling?

Would be useful to shut down the economy of spawnpoints, familiars, and the ubiquitous Battle Forge. Or maybe even hurt a mage themselves for mana. Of course it'll be a quick target for a dispell, but so are a lot of other enchantments like a Ghoul Rot, Finite Life, Mind Control, Magebane, etc.

So would this be something viable?

Closest to the spell you are describing is [mwcard=MW1J14]Mana Siphon[/mwcard].

Each time, something that cause Upkeep +X it feels to me more like my chanelling was auto decreased
