Swell, cool, cool 
I am only stating the facts, no need to get your panties in a Twist.
Like I said, stealth mechs followed by that magnetic windfury token can finish matchup easily BUUUUUT not that many people run it and you can always run Asphyxiate to deal with those.
TL:DR double Blood DK has advantage over Handbuff Paladin but you won’t see that deck often because it has weaknesses against other classes and is not an optimal deck for the class overall.
I want to beat anyone in this unfair game 
Lesser action is almost always better than inaction.
Viper the first weapon if you can. That’s a given.
To truly defeat them, you must first viper the weapon within your own heart.
It may not happen often, but I did manage to survive the 35 attack Leroy (thank to primus eating another giant minion) and then steal it and smash the paladins own face. That felt very rewarding.
(Playing handbuff dk, fwiw, not bbu).
Yes, you can also get additional survivability in control DK from Ignis Weapon.
Handbuff Paladin is super strong but BB DK is his weakness. BB DK is almost non existent tho because it lacks any win condition, lacks draw, cannot play Vampirc Blood if it splashes U for Helya and is struggling against infinite resources of Druid and Priest.
Highlander Warrior, thank you very much
