{Dragonstorm}???
Why?
I do not see the red mana to cast this card or any dragon, since {Progenitus} is a hydra

[Mattao19]

{Balzing Shoal}

[ibtrickey]

Okay, but how do you cast progenitus???

[Agrus Kos, Enforcer of Truth]

Okay, but how do you cast progenitus???

{Blazing Shoal}...

[ibtrickey]

So blazing shoal is the only reason those 5 cards are there?

[griffin131]

Yes. And they result in 1 turn kills.
Not Turn 1 kills, but from 0 poison counters to 10 in one turn.

[SoshiGanrou]

So blazing shoal is the only reason those 5 cards are there?

Yes. It is a huge boost on the swing for the agent to end the game quickly.

[ibtrickey]

Thanks guys.
I was a bit confused:)

[Munchlax]

So kill the 4 blighted agents and this deck can't win?

Ink moth nexus

[Mattao19]

Good luck killing them {Abrupt Decay} wasn't a card back then and he has counters for days!!

Fortunately {Blazing Shoal} has since received the banhammer.
