Pawn

Advance - {t}, put an Advance counter on Pawn
and add {u}. If this is the first time Advance
is activated, instead put two Advance counters
on Pawn and add {u}{u}. If Pawn has six or more Advance counters, sacrifice Pawn then create
a token copy of Queen, Rook, Bishop, or Knight.

attacking or blocking pawn creature.
