This is a 4 mana rogue weapon. On average your opponent gets a 2-3 attack minion and this will be a 3-4 attack weapon. In 'best' case scenario, your opponent summons Ancient Watcher or Millhouse Manastorm and this becomes a 5 attack weapon but chances are slim.
@Rajiner: Only one collectible card, optionnaly with associated tokens (as many people did this week)
I know a Magtheridon has already been submitted this week, but since I posted my card in the discussion topic before the other Magtheridon has been submitted I don't think this is an issue.
In WoW, Keli'dan the Breaker is the final boss of Blood Furnace. He is the one responsible for using Magtheridon's blood to empower fel orcs, obviously against Magtheridon's will. Magtheridon can be freed by players in a raid, and will thank them by trying to kill them.
The scene is that Sea Reaver jump into random spots in the marching army, and the Sea Reavers's cruel leadership whip some speed into the maggots (the cards*).
Giving Sea Reavers some play and sometimes a wanted AoE effect.
You may overdraw if the Sea Reavers are randomized deep into your deck, but that's the downside of this card. Could make mill warrior a thing, but sometimes your opponent get the Sea Reaver in his top 2 cards and you might need 10 cards to draw one, but can also be vice versa ofc.
