What the hell does "the inception strategy" refer to?

It was based around Extract and Praetor's Grasp effects and was astonishingly effective against fast glass cannon meta standard staples like Flash Hulk. The game plan revolved around playing a more conservative game and tutoring for wheels and exile from deck effects rather than combo pieces early in order to neuter the fast glass cannon combo decks at the critical single point of failure (for example, Narcomeba/Eldrazi against Shuffle Hulk, or Jace Maniac/Lab Maniac versus Doomsday/Consultation decks). Many of the older meta standard staples had multiple critical points of failure in their typical lines of play, any one of which could be compromised to completely eliminate that deck from contention in the match in any relevant way at all.

After the printing of Veil of Summer this tactic become less effective as it relies on blue and black player target exile/discard effects and Veil obliterates the line of play when it's in opening hands or tutored for instead of combo initiation elements by fast glass cannon combo decks. For about a year and a half Inception was the most dominant deck in the entire format but new tools have made that game plan less attractive in competitive settings. Some of the principals are still sound and effective, but the specific tactic relating to targeted discard and exile spells no longer is.
