Spot removal and countermagic in particular are at an all-time low, since the current ramp suite is good enough to simply overpower aggro decks with bombs, sweepers, and incidental lifegain
However, heres one definite piece of advice
It does seem as if every set has a preferred trainer, and for Phantasmal Flames it definitely seems to be Dawn
Afterwards, the cards are revealed one-by-one, requiring another finger swipe to move to the next card, allowing you ample time to inspect each one
Marauding Blight-Priest never seemed so powerful
Rush of Inspiration / Crackling Falls is a better card, but Suppression Ray / Orderly Plaza gets the job done in the end
