News is starting to drop about the future of all the Blizzard franchises, and the first cab off the rank is Hearthstone with a 25 mana card. Because you can't cast it under normal circumstances, players will have to lower its cost through casting spells to make it more playable.
It's called Shirvallah the Tiger, an ancient spirit that's exclusive to Paladins.
It will also introduce a new keyword called "Overkill". This is a 0/3 Rogue minion which, like all Spirits, has Stealth for 1 turn. Overkill allows a card or player to receive a certain bonus if they deal more damage to a minion than it requires to kill them.
Rumble Run: FREE single-player content that tests your might against a colorful array of Rumble champions. Apparently axes will be involved.
