Why Bard is favored
After Rocket Grab(Q) misses, Bard can pressure during its downtime with Meeps(P) and Caretaker's Shrine(W), then use Cosmic Binding(Q) or Tempered Fate(R) to create a catch. A Bard matchup breakdown identifies the window when Blitz is not hooking as Bard's chance to take over lane.
How to play as Bard
Keep a minion between you and Blitzcrank while Rocket Grab(Q) is ready, and do not open Magical Journey(E) toward him; Bard players identify minion cover and avoiding a tunnel in front of Blitz as key safety rules.
When Rocket Grab(Q) is unavailable after a miss, Bard can trade with meep-enhanced attacks and heal allies with Caretaker's Shrine(W).
Cosmic Binding(Q) can stun Blitzcrank if its missile hits him and then collides with a wall or another enemy.
How to play as Blitzcrank
Keep Rocket Grab(Q) ready until Bard steps out from minion cover; if the hook misses, respect his poke and shrine sustain during its downtime.
