Buckled In

When Buckled In enters the battlefield, you may
tap an untapped Archer you control. If you do,
search your hand and/or library for a card named
Scott Lang, put it onto the battlefield, and
transform it. It gains haste until end of turn.
Shuffle your library.
Sacrifice Buckled In: Target creature gains reach
until end of turn turn.
