You can get some thematic ones, like Gyre Sage in +1/+1 counter decks, but the combination of any color and hexproof makes this a reliable dork for any deck
"Adeline, Resplendent Cathar" gains power for each creature under its owner's control, while "Darling of the Masses" creates a Citizen token whenever it attacks
(2025-06-06) If a card copied by the token had any "when [this permanent] enters" abilities, the token also has those abilities, and they'll trigger when it's created
Additionally, theres the issue that there simply may not be someone within your area that wants a card
If you enchant your [c]Pestermite[/c] with [c]Splinter Twin[/c], then you can tap Pestermite to create a copy of itself, and each copy will untap the original Pestermite, and then you can repeat the process as many times as you want
