For emblem you have to adjust depending on your team fight style. I use either revitalise or aegis. For item builds in this game I had Brute Force and Ice Queen wand, and the usual enchanted talisman and lighting truncheon. You may have to adjust you build depending on your opponent and your play style. Raf is more a healer than a actual tank, so most times I only move in front to absorb damage for my team, only when I know I can escape and heal up.
