Miracle Sprint Rogue Legend

General Mulligans

Backstab is typically always good to keep to combo with other pieces such as SI Agent on turn three or elven minstrel turn four.

Firefly always good to keep regardless of matchup in order to establish board control and keep a cheap combo card for later

Hench gang is an early threat on turn three. Just don't attack with your weapon until turn three and you'll activate "the thug" twice by turn five (theoretically)

Feldorei is the MVP of the deck. Turn four good body of stats especially vs priest and allows for potential comeback vs difficult aggro matchups

Sometimes it's good to keep SI agent if you already have a Firefly or backstab to pair it with. 

Van Cleef can be a serious threat if you have the cheap cards to play it by turn 3 or 4. 

Sometimes you can keep minstreal for card draw and if coin out turn three. 

Fan of knives is more specific to odd paladin. It could swing the board and win the game.
