You already have Dai Li Agents but lack support.
Prioritize Badgermole or Raucous Audience.
Counters on multiple creatures. Stacking every counter on one land helps combat but only counts as one creature for Agents.
You have Dai Li Agents and can use the interaction.

Agents can earthbend two different lands. Badgermole gives those counter-bearing creatures trample so small blockers cannot absorb all their damage.
The support is missing
Keep broadly useful creatures and answers; if the special reward is missing, build a complete deck before chasing it.
