Overview
Mastery is a system introduced in July 2016 (version 1.5.8) to separate players into Tiers, based on the number of cards they have mastered.
Cards are mastered by gaining experience for those cards. Winning Story Mode and Event battles give the cards in your deck experience, or XP. Higher rarity cards take more XP to master, but award more Mastery points. Since January 2019 (version 3.2), XP gained in cards is also gained by the player, and counts toward the player's Level.
Mastery Tiers
There are four Mastery Tiers: Bronze, Silver, Gold, and Platinum.
When opponents are selected for you to face in events, they will only be selected from within your Tier.
Playing an event at higher tiers earns better rewards (more 
, 
and 
), but pits you against stronger PvP opponents.
A separate Mastery tier is maintained for each Color. When you enter an event, you are placed into the highest Tier among your colors that is represented by a node in the event.
Example: If an event has a Red Node, a Green Node, and a Black Node, you are placed into the highest tier you have reached between Red, Green, and Black.
Mastery Points
When a card reaches full XP and becomes Mastered, you gain Mastery Points for each of the card's colors based on the card's rarity. Colorless cards provide half of the usual Mastery Points, but for all 5 colors.
Once a card becomes mastered, you can never gain any more experience or Mastery Points from that card.

Strategies
- Since the PvP competition gets significantly harder each time you tier up, it is usually recommended that players do not go out of their way to tier up until they can win matches consistently at their current Tier.
