MTG Salvation

What’s the best way to make progress in mtg Arena on mobile?


I’m a long time paper player, new to Arena on mobile and feel way behind since people have been collecting cards in the desktop version for years.


So, what’s the best strategy for building a collection or particular deck?


Is there a daily thing to make sure I tap through? Quests? Certain game types?


What’s the best way to approach in-game currency? Is there a correct way to put real dollars into the game?


Thanks for any help your experience can provide!
