I think this card should be like
Battlecry: summon 2 secrets from your hand to battlefield.
Deathrattle: summon 3 secrets from your deck to battlefield.
This even seems better for me

at least they have to have some secrets on their hands to have instant effect. =)
Maybe some of your decks are quite good against clearing those 1/1 drops that come with 1dmg 4 durabilty weapon but its mostly hard with all the GET DOWNS :D!!! i dont that card needs a small change. I mean even every rank has paladin spam and that even shows how unbalanced it is jusat by that.
