Your Win Condition
You should be favored at all stages of the game against Zac, but it is very losable.
General Strategy
Rush Executioner's Calling early. Do not chase him down and tank the minion wave.
Trading Patterns
Zac's Q (Stretching Strike) is tricky, but bufferable. If he Q1's a minion or you and is about to smash, press E to ignore the smash animation. Zac's E (Elastic Slingshot) is also bufferable: if you see him casting E from fog of war, catch him out midair. Zac R is bufferable, but fighting him while he is ulting is not advised because he picks up blobs easily. Step on his blobs to deny his HP regeneration.
Wave Management
Their Win Condition
Zac wins by gaining infinite sustain by picking up his blobs. He deals a deceptively high amount of damage.
