Resolve both Twilight Drover abilities, creating four 1/1 Spirit creature tokens.
Activate Kykar three times by sacrificing three Spirits, adding 3.
When the Spirits die, Twilight Drover triggers three times, putting three +1/+1 counters on it.
Repeat.
This loop turns Twilight Drover into an unstoppable engine by leveraging Illusionist's Bracers to double its token-making ability for the low cost of a single +1/+1 counter. As those newly forged spirits hit the graveyard, Kykar, Wind's Fury steps in to sacrifice three of them for red mana, which fuels the payment while simultaneously triggering Twilight Drover's counter growth to keep the cycle going. To round out the operation, Chromatic Orrery ensures that the raw energy you generate can be immediately filtered into any color of mana you need to sustain the loop or fund your broader game plan.
