Barricade can help you keep up your block; if you're able to outblock the damage you can slowly build it up turn by turn. This can then combo with Entrench to double your block and take it to crazy high values, up to 999, making you practically immortal.

Despite being block focused, this deck still needs to deal damage. Body Slam is an obvious win condition if you can get Barricade set up. An alternative is Juggernaut which allows you to slowly whittle down foes as you turtle, though the fact that it hits random targets makes this less reliable on certain multi-foe encounters. You can of course take both and have the best of both worlds but this isn't required.

Once Barricade is online, cards that generate huge block in one turn (such as Impervious and Second Wind) go from situational to game-winning. Smaller sources of block can work fine too and are useful for triggering Juggernaut repeatedly.

Disarm and Clothesline can reduce the enemies' damage, also helping to protect your block.

Thinning your deck down with exhaust effects throughout combat can allow you to find your Entrench more often, if you are running it. It's possible to stack up a bunch of block, exhaust virtually everything except Body Slam, then cycle it repeatedly to finish the fight.
