Upgrading a card will change the visuals of the cards in distinct ways for each upgrade.

Upgrading a card is also how you increase your Collection Level, which unlocks new cards for you.

You can level up from Common to Uncommon, Rare, Epic, Legendary, Ultra, and finally Infinity.

Higher level ups grant a higher increase to your Collection Level.

As you increase each rarity you will see the character frame break, parallax, start animating and have extra visual effects, have a shiny logo, and animated Border.

Rumor has it something extra special happens when you upgrade to Infinity…
