For Daisy, does the cost reduction count as 1 per? or up to 1 per token? So can it be more than 4 reduction?

To determine how Daisy's cost reduction works, we look at her ability: "Reduce my cost by [1] for each of the following tags among your units — Bird, Cat, Dog, and Poro."

According to RiftJudge FAQ #10255, the reduction is based on the number of unique tags present among your units, not the number of units themselves. If you have multiple units of the same tag (e.g., 3 Bird units, 2 Poros, and 1 Cat unit), you have three of the four required tags present on the board. In that scenario, Daisy receives a discount of 3 generic energy.

Since there are only four specific tags listed (Bird, Cat, Dog, Poro), the maximum possible cost reduction for Daisy is [4]. Having multiple units with the same tag does not increase the discount beyond the number of unique tags represented.
