Ionic Bond

Bond 2 (Enchant two target creatures you control.
Those creatures are bonded and count as two creatures
and one target. They must take all actions together, including: tapping, attacking, blocking, and crewing. )
One of the bonded creature gets a +1/+1 counter,
the other bonded creature gets a -1/-1 counter.
"An ionic bond is when a metal donates an electron to
a nonmetal and the two particles are electrostatically attracted to each other."
