The Card Styles Button has returned with some updated functionality.

This should allow easier customization for how you’d like to visualize the components of your deck.

General

Purchases from desktop players in Japan will now be charged in Japanese Yen instead of United States Dollars.
Golden Pack progress will be awarded for purchasing Modern Horizons 3 packs from the store, though the Golden Packs themselves will not contain Modern Horizons 3 cards.

Rebalanced cards with the Viashino or Cephalid type now have the Lizard and Octopus types, respectively.
Tweaked the Cast with Emerge browser.

In Modern Horizon 3 Store Boosters, Special Guests replace a common at the same rate as in Play Boosters (1 in 64).

When Temporarily Banning a card, Card Styles of the card will also receive the red overlay communicating their temporary banned state.
Sparky no longer teleports to different locations throughout her tour of the features in the game.

Grinning Ignus is back to giving the right amount of mana. Grinning Ingus continues to not exist. Is there a more mispronounced Magic card? (ed: I know a chef that would like a word)
Mana Drain wasn’t producing mana after countering Nexus of Fate. Now it does!
Fixed an issue with Ivy, Gleeful Spellthief where spells that could target something else but weren’t didn’t get copied for Ivy. Repulsive Mutation now works how you wanted.
The third mode of One Last Job was letting people choose invalid targets (generally creatures with protection). Now it doesn’t.
Face down shapeshifters with ETBs were still triggering. Moritte has been chilled out.
Molten Impact’s boon was doing weird stuff. If you play Gladiator you already knew, and if you don’t you probably don’t care. Anyway, it’s fixed.
Addressed an issue with changed supertypes modifying types.
There was a crash that involved being Hexproof, controlling the other player, and then playing their Gaea’s Blessing. Now you can play out this very common scenario.
Grenzo losing abilities with Heist on the stack no longer causes issues.
Closing and reopening the cast browser for Adventure cards you’re casting but don’t own was making the second option vanish from the browser. Now it sticks around.
