Turn 2 warlock kills.. ? nerf it!

Discard warlock needs nerf on the “Tiny Knight of Evil” ( discard a card gain +2/+1 )
the so i seen this a couple of times… and i wonder why its even possible… it does need some luck on draw

but warlock starts with the coin and if you dont have some serios 1 or 2 cost here youre dead before your 3rd turn

warlock coins in the knight and for 0 mana discovers tempoary card 2 times both times getting the “boneweb Egg” ( deathrattle summen 2 spiders with 2/1 when discarded )

this gives them a first turn with a 7/4 knight and 4 spiders with 2/1

you didnt have a 1 cost and low and behold you didnt get a 2 cost… so you shaman up your totem of healing -.-

then warlock have 3 cards on his second turn and discards lowest cost card to give all minions +1+1… TWICE

now he spend 4 mana on his 2 turns and can smak you in the face with a 13/8 knight and 4 spiders with 4/3 for 29 dmg and yeah… WTF

has the game really evolved to turn one play half hand… turn turn empty your hand and do 29 dmg ???

what 3 cost card are you suposed to play in counter of this… if any cards at all can even counter this play ???

perhaps its the Catacombs card that need to cost 1 mana instead of 0 ( discover a card make it temporary )… .but i fail to see any card combinations that can counter this tupe of start… even if they discover other than the spiders example the 3/4 or the 2/5 taunt

the first turn on coin simply pumps out stats worth of 10- 15 mana

With all the op Discard Warlocks Wild feels unplayable atm.
