WWE SuperCard Senior Producer has posted the following on the 2K Forums, adding more information on the SuperCard WrestleMania Update.
1. Wrestlemania Tier
Wrestlemania cards are here! In addition to the new cards there are new deck rankings above Survivor++: Wrestlemania, WM+, and WM++. As with previous tiers, advancing in these new tiers allows WM cards to drop from the board and in King of the Ring you win WM cards as rewards. You’re guaranteed a WM card from the board when you get to the Wrestlemania tier, and the reset counter will guarantee you a WM card after a certain number of board resets (just like in other tiers).
2. Daily Login
The Daily Login will give you a chance to earn 5 cards each month simply for logging in! On the 1st of each month, 5 cards from the general pool of cards will be available as rewards for logging in a certain number of days during the month. The cards include 1 Uncommon, 1 Rare, 1 Super Rare, 1 Ultra Rare, and 1 Epic. You don’t have to login consecutive days, but you’ll need to reach certain “total days logged in for the month” goals to win the cards. On the 1st of every month your login counter will reset to 0 and 5 new cards will be available for the new month. The roll over to a new month is all based on UTC time (Pacific Daylight Time + 7 hours currently).
3. Card Cap to 130
We have increased the card cap to 130.
4. New MyCards User Interface
The MyCards UI has been changed to handle larger amounts of cards in MyCards. This not only should reduce out of memory issues (crashes or game slowdowns), but is easier to use now.
5. Card Locking
You can now lock cards in your MyCards list removing them from training, combine, and deletion lists. Simply lock a favorite card and you no longer have to worry about accidentally training something away.
6. Card Pack Change
Beginning on March 26th, 12am PDT, the Legendary Card Pack will drop Wrestlemania cards in addition to Legendary and Survivor cards. The chance for the higher tier cards to drop is less than the tiers below. Good luck!
