How to beat Mordekaiser as Zac: the early game

Mordekaiser bullies you from level 1 — his passive (Darkness Rise) AoE and Q (Obliterate) chunk your blobs every trade, and his W (Indestructible) heals back what you deal so you lose extended exchanges. Don't try to trade blow-for-blow; last-hit safe, build MR, and eat harass with your passive rather than feeding his shield.
