I would pick 3-4 really important creatures, like Vito and indulging patrician and bloodthirsty aerialist, for the deck's theme and include 4 copies of them (except legendary creatures since you are only allowed to have one of them on the board at a time and you don't always want to draw a second one to just hold in your hand forever, so maybe drop it to 3(?) or keep at 4 if you think it's important enough)
Live market values for cards in every official region pick yours to start
Smaug the Magnificent does just that because creating a treasure each turn is already big game
You can only choose one of them, but each is potentially pretty powerful and useful in different situations
It thrives in rocky terrains, using its strong grip to climb and defend itself with ease
The upside, however, is that it allows you to copy your powerful tokens and overwhelm your opponent, which makes Populate cards worth adding to your deck
