You have the payoff but too few ways to activate it.
Look for Waterwind Scout.
Use Scout’s Map to explore: revealing a land can put a land from your hand into play tapped; a nonland grows Nicanzil.
Your synergy is already working but you keep falling behind.
Take an early play or answer before another expensive reward.
Explore is not always a counter. If your plan needs a bigger creature, account for revealing a land instead.
The support is missing
Favor castable creatures and interaction if narrow support does not arrive.
