Can nothing stop the swarm?

[Point Blanks]

Here are a few armies I thought up to fight the 4th mass horde:


Dund
Syvarris
2X reavers
Krav

If Dund can take out the order markers of the horde, there will be a lot of minutemen just standing around, ripe for picking. If you add the reavers into the mix, your opponent will have a hard time attacking your range attackers. Syvarris greatly outranges the enemy, and with his double attack he can take out two per order marker. The Krav also outrange them, and with their stealth dodge they can stay on the board a long time.
Another variation is:

Syvarris
Krav
AE
Raelin

You outrange the enemies, and raelin keeps all your guys alive with the plus 2 defense.

To take on the Marro horde, I have this all hero army:

Krug
Raelin
Sgt. Drake
Criuxus

another army is to use

Izumi
Tagawa
Raelin
Guilty
Dund

Your samurai counterstrike the marros, and with raelin their power is vastly improved. Because your opponent has to place all their order markers on the same card, Dund can immobilize them. Guilty rounds out the army, and can stay alive for a relatively long time if he has height advantage and raelin.

If you want an all defense army against the hoarde, this can work for ya:

Raelin
2X sentinels
2X Ashra
