Oh my, this is a good card.
It is pricey and unique but 2 power for 3 cost with a benefit instead of a debuff is better than the norm for support cards.
And altough the action effect is somewhat situational, forcing either you or your opponent to have a deck that works with it, it is a good counter against dwarwen decks using reclaiming the fallen and maybe even discarding dark elves decks.it out
Major weakness is of course that it is an expensive support card exposing you to support destruction.
Will try it out in 1,2 or even 3 copies in a standard orc rushy deck with swarm of bats and blood dragon knight added.
