They'd all love having access to the doubling ability of Orfeo, whose ability sort of has haste, too, because you get to trigger him the turn he comes into play (assuming he's played in the first main phase)
I must say, Liga Smilshkalne, now has my second favorite counterspell art of all time, behind only the original Force of Will by Terese Nielsen
Whether Warlock Class will see play outside of Virtus & Gorm and other decks that use Quietus Spike is debatable, but again I like it for Liesa because it comes down early, and levelling it up wont cost me life
Probably works best in Group Pain decks like Mogis, God of Slaughter and Rakdos, Lord of Riots, though those decks have access to Black so you already have great card draw
Dragon Pokmon are strong against : Dragon Pokmon
