You already have Bitter Work but lack support.
Prioritize Raucous Audience or Ostrich-Horse.
A four-power attacker, not only ramp. Too many mana cards and no threat leaves you drawing air; a tapped land cannot also attack.
You have Raucous Audience and can use the interaction.

Bitter Work’s exhaust makes a four-power land. That land turns Audience into a two-mana source and can trigger Bitter Work on attacks.
The support is missing
Keep broadly useful creatures and answers; if the special reward is missing, build a complete deck before chasing it.
