Hopeful Tune, Rektina

[AUTO]:When this unit is rode upon by a grade 3 card with "Lianorn" in its card name, choose one of your vanguards, and reduce the cost of that unit's original [AUTO] ability by [Counter-Blast 1] until end of turn. [CONT](RC):If your vanguard is in the UnisonDress state, this unit gets "Boost", and can intercept from the back row.
