Zhou Yu can't attack unless defending player controls an Island.
Zhou Yu is essentially a 7-mana 6/6 vanilla beater whose only text is a restriction, so he's a color-identity figurehead for a mono-blue deck rather than the engine. You win by leaning on blue's strengths—card advantage, counterspells, bounce, and tempo—while the commander is just an occasional finisher (he can swing if you give an opponent an Island via fixing-hate or your own donation effects). Play him as a control or tempo shell that grinds the table out and closes with a real win con.
Since the commander adds nothing, invest your budget in the best blue staples: fast mana (Mana Crypt, Sol Ring, Mana Vault), premium counters (Force of Will, Mana Drain, Fierce Guardianship), and tutors (Mystical Tutor, Personal Tutor) to assemble a compact win like Thassa's Oracle. Consider treating Zhou Yu purely as a 99-card-deck color anchor and ignoring his text entirely—you'll get more power swapping toward a tighter combo-control plan than trying to make a vanilla 6/6 relevant.
