doublade
would have put gligar here but i remembered it kinda sucked in sm without immunity + defog. as for doublade, one of the best steel types ru has ever had, been very solid since the start of sm till it moved up in the late usm. could do almost anything between defensively checking a ton of threatening pokemon like virizion, pursuit trapping gardevoir when it was at its peak, sweeping with sd etc. been consistently influential and a tier staple throughout its 2 year tenure and could probably earn a spot in the top 5.
