If I were going to play a straight Orc deck, I'm going to want the fewest cards possible so I can draw into my Waarghs and other monster cards which in the right combination can burn an under-defended zone with one combat phase. Hit fast, hit hard, hit often. With a Dwarf deck I'll probably play a more medium sized deck, heavier on tactics than I might otherwise play, because the supports and units can withstand so much damage, I can outlast a number of my opponents just by playing conservatively and using my tactics to control tempo.
Different deck sizes for different builds, races, and strategies.
I think all races can control temp in some way (Some are stronger than others)...Dwarves have damage reduction to capital and troops. Chaos has corruption and discard effects. Orcs have mass creature kill and support destroy...Empire has tactical control and mass destruction card.
