A calculator for Anyfin Can Happen, inbuilt to Hearthstone Deck Tracker. NOTE: This currently only works with Hearthstone Deck Tracker v0.13.12+ (more specifically commit ed3aa02 and later), due to a new API method being used in it.
Whenever the card "Anyfin Can Happen" is hovered over in the player's hand, it will display a quick overview of how much damage it will/could inflict onto the opponent (just counting murloc damage). This takes into account the possibilites of murlocs being summoned, showing the possible range of damage. This would include murlocs on the board, but not other minions.
#Sweet, that sounds awesome. How can I use this?
Wherever you have Hearthstone Deck Tracker installed, drop the AnyfinCalculator.dll (available in the releases folder) into the 'Plugins' folder. Then run Hearthstone Deck Tracker and enable this plugin in the plugins menu, and ta-da! If the plugin does not show up in that list, right click the '[PLUGINNAME].dll', go into Properties and click "Unblock" at the bottom.
