Right now I have it in so that I have something good to return with The Mending of Dominaria, but maybe a better plan is to use Bone Dragon and not The Mending of Dominaria, either just relying on Devious Cover-Up or possibly using Bone Dragon to sculpt your graveyard for Gaeas Blessing, though that sounds like the kind of late-game nonsense that will never actually come up, whereas Gaeas Blessing messing up your Bone Dragon will come up
While the three decks are carefully balanced against each other, they each focus on differing play styles - corresponding to their different combinations of two ink types from the six card colours in Lorcana - so some may be easier to handle or more satisfying if you prefer to play a certain way
If a pack has an EX or an alternate art card, it will cost 3 Stamina
You can also play Field of the Dead and Scapeshift to mix up your strategies, assuming neither of those cards gets banned
If Wizards didnt put an acorn on it, its fair game
