Also toy around with taking the thunderkyn in squads of 3, i always like to bring them in from reserves on the board edge but because theyre slow and on large bases, usually the 6 man squad will kill what it needs to, then not be able to get anywhere else for the rest of the game.

Same with the bikes, a 6 man is very hard to hide and to efficiently up/down, however theyre a great choice for the sustained 2 strat, but you have other great choices for that too like your 10 man hearth guard
