Vampire
I was thinking that this card is the weakest card because Vampire has 1 health and after looking at the stats of this card l realized that it's one of the fastest card in the game. Every time Vampire hits monsters his health increases that's why his name is Vampire. If Vampire decreases 3 health of the opponent monster then his health will have +2 health which is not bad. Apart from that this card can be hardest to hit because it's the fastest card in the entire game. No card has 7 speed in the game. Additionally having flying ability makes almost impossible to hit this card with slow range, melee attack monsters.
