How it works
Activate any number of Elves you control by tapping them, adding at least 4.
Each Elf tapped this way triggers, untapping it and putting a +1/+1 counter on it.
Activate Temur Sabertooth by paying 1, returning Dionus from the battlefield to your hand.
Cast Dionus by paying 3, which enters the battlefield as a new object, thus granting a fresh instance of the ability to each Elf you control.
