List of Undeads that can be summoned with this card:
Good draws for any deck: Spectral dragon (10G/10R), Necromancer (10G/10R), Ice revenant (10G/10R), Bone dragon (10G/10R), Dark knight(10G/10R), Koschei (10R), Necropolis (10B O_o), Undead cavalry (10G/10R), Lich (8 stock, full cost), Necroent (10G/10R), Stalker (10G/5R).
Situational draws: Army of darkness (10G), Corrupted woods (8 stock, full cost), Undead host (10G/10R), Risen angel (9G/10R), Hungry dead (8G/8R, full cost), Fallen knight (10R), Spectral siren (10G), Deathwood shaman (10G/10R).
Bad draws for any deck except Undead: Banshee (9G/9R, full cost), Corpses behemoth (10G/10R), Emissary of the afterlife (10G/10R), Eternal guardian (1 stock, full cost), Unholy shrine (10B), Vampire (10G), Vampire countess (3G, full cost).
REALLY bad draws: Vampire lord (10G/10R).
So this card gives you a card in hand and some resources to play it (or another card). In 10 cases of 27 it will be a rare which can be played or turned into more useful by Veteran militia. In 12 cases you'll get 10G/10R, in another 7 - full or almost full cost of summoned card, so even if you wasn't lucky with Crypt and got Emissary of afterlife - resources are almost always welcome. So this card is good in many decks, not only in Undead.
I'd like to see something like Flame obelisk instead of this form.
