The combo is Seismoid first, then Kujata into more Mechs and a 2nd Kujata to get even more Mechs out and as soon Mechaz0r and Silver are on board your puny Mechs don’t die to Kujata anymore because of Forcefield.
Progenitor just offers crazy value if they don’t have AoE. With that huge of a board they often can’t answer Mechaz0r and the swarm and lose.

Rebuke activates Frenzy, that can be used to remove minions or deal face damage, especially with Mechaz0r’s Airdrop.
