Vehicles you control have Reconfigure {x}
({x}: Attach to target creature you control; or unattach
from a creature. Reconfigure only as a sorcery. While attached, this isn't a creature. X is equal to its mana
value.)
As long as the reconfigured vehicle is attached to another vehicle, that vehicle gains power and toughness equal to the reconfigured vehicle's
power and toughness as well as any activated or triggered abilities.
