This particular card is from the third release set for the trading card game, Fossil Set
Edric, Spymaster of Trest Edric, Spymaster of Trest leverages blues many unblockable creatures, like Mist-Cloaked Herald and Slither Blade, to slip through your opponents defenses and rip through the deck to chain together extra turn spells, and eventually conclude the game with a Beastmaster Ascension or something
There are a ton of use cases for this card, and itll only get better with each subsequent set released
