Tunnel Effect

HYPerlink Cost
Link at no cost, if possible, a module you control with link cost 3 or less.
BasE Power
guardian CaRD

As the wave manifested itself, the particle hid behind it and traversed the prison walls.

  • Linking via Tunnel Effect must be performed when the ability resolves. The effect terminates once the second link is complete, and does not last until end of turn.
  • You can only link and hyperlink modules of a domain that matches one of your active Guardians.
  • This ability checks the current value of the link cost, including modifiers.

The microscopic world challenges our common sense: quantum particles can traverse walls! In fact, probability waves still wiggle on the other side of the wall, leaving some chance for the particles to escape. Scientists used this effect to build microscopes that reach the smallest scale we can imagine: the scale of an atom. Will we ever be able to zoom in further?
