Grimstroke + Pangolier

Why this works

Setting up for a good Rolling Thunder is much easier when your targets are leashed together. Grimstroke's Soulbind forces two enemies to share a fate, which creates a perfect opportunity for Pangolier to roll through both of them. Even without the ultimate, a well-placed Swashbuckle can hit both bound heroes, and the slows from Stroke of Fate make it harder for them to create distance. The combo isn't about duplicating a spell; it's about Grimstroke creating a clumped, slowed target for Pangolier's area damage. Ink Swell adds an AoE stun to this, giving Pango an even better window to connect.

The plan looks for mid-game pickoffs on multiple heroes at once. Grimstroke has to land Soulbind on two important targets that are close enough for a follow-up. Pangolier then needs to be in position to commit his own abilities. The weakness is that it requires coordination and for enemies to be out of position together. If Pangolier gets controlled before he can act, or if the targets can split before Soulbind lands, the whole sequence can fall apart. It's a decent plan that can pay off, but it's far from a guaranteed teamfight win.
