How does it affect kci and ensnaring bridge strategies? They already had decay/pulse/kcommand to deal with – so inversely I guess the question is does trophy flat out replace decay/pulse in any deck looking for those effects? Implications for kcommand are less obvious since it really does a different thing; but being maindeck artifact hate was certainly a good part of its value.

I think there are two other cards that along with trophy will warp modern: unmoored ego and knight of autumn. These 3 cards represent efficient versatile answers to moderns weirder angles of attack. Tron, valakut, bridge, bogles lose a lot of their edge when these versatile/maindeckable answers come out to play.
