Edit "deckbuilder" card selection

[BUtch711]

Thank you for your great work

Could I have a breakthrough of how to add/personalize the "deckbuilder" card selection. How to I add / remove cards

I wish my deck builder options would be exclusively 93/94 magic

I wish to add the following cards:

Mana drain
land's edge
dance of many
gravity sphere
Hell's Caretaker
power artifact
chains of Mephisto...
recall
sol'kanar swamp king
