WIGHT LORD NEUTRAL DESTRUCTION Cost 5 P 1 H 4 Necromancy Action: WHen this unit enters play, destroy target unit in any corresponding zone
BLOOD DRAGON KNIGHT NEUTRAL DESTRUCTION Cost 4 P 2 H 4 Action: When this unit attacks, deal power equal to power to target unit in the defending zone.
When I have build destruction decks and wanted some control element in them the choice has often been between these two units.
There is similarities between them but yet they are not inchangeable
Blood dragon Knight is cheaper which is the strongest advantage over Wight Lord. It will nearly always kill a unit with 2 or less hit points on the same turn it is played. It must normally be played in battlefield or be helped by other cards to be effective. It is a standard 4 point card with 2 p, 4 h which can aid in attacking. The other advantage over Whight Lord is that it can use its ability next turn if not destroyed, corrupted, taken over, rended immobile or moved to another zone.
Whight Lord is costlier but has in my oppinion stronger abilities. It is the only card in the game so far I know that can destroy target unit without any prerequisites (other than playing it in corresponding zone). No other card can unaided kill every aviable unit in the game. If played in kingdom or questzone it also helps with gaining resources or cards. The Necromancy ability will at least put second thougths of removing Whight lord i the card is helping with resources. Whith different sacrificing techniques the wight lords ability can be used again and again even though it is quite costly to do so.
Which of the cards do you prefere to use in which decks?
