Lier turns off counterspells for everyone, but I play counterspells that exile or return to hand/top of deck. Flashback gives cantrips a double boost. Most spells are instant so they can be played on any turn.
Willowdusk doesn't care if you gain or lose life. So every card in the deck (except basic lands) does one of those things! Big swings = big gains, sometimes not until next turn, but they have to answer it or they will die.
