Every time you play a non-token dragon, Miirym just gives you a non-legendary token copy of it, meaning you get double the threats for the same mana investment

Indirectly, it's useful in a lot of other ways

It costs no mana once its in play and can dominate games

Sure, there are better options, but Budoka Gardener still finds its way into lots of decks for having a fairly low mana value and also being somewhat of a late-game threat

Players can't respond with a spell or ability that removes counters to prevent you from drawing a card and scrying 2

The bonus part of this is they arent exiled under Tinybones , meaning they arent lost when Tinybones is killed
